• Valves manufactured in accordance withthe requirements of ASME Boiler andPressure Vessel Code Section VIII andSection III.

• Superior seat tightness. Precision lappedflat metal-to-metal seats, or elastomer orTFE O-ring soft seats provide the ultimate in seat tightness. (Elastomer or TFE O-ring seat standard for Series BP.)

• Maximum corrosion resistance. Trimcomponents are stainless steel asstandard. All 316 stainless steel, Monel®,Hastelloy® and NACE* optionalconstructions are available.

• Spring standardization. Standard Series800 and 900 pressure relief valves aresuitable for inlet temperatures to 750°F[399°C], using a 17-7PH stainless steelspring. Series BP is suitable for inlettemperatures to 400°F [204°C].

• Fewer parts result in increased reliabilityand ease of maintenance.

• Series 800 pressure relief valves have anexternal blowdown adjustment allowing for short blowdown, smaller differentialbetween operating and set pressures, andreduced product loss.

• Series 900 valves use a single trim designfor liquid, gas and vapor services.

• Series 900 valves provide reliableblowdown without the need foradjustment.

• The Series BP with its balance pistondesign offsets the effects of variable backpressure on valve set pressure.

• Series BP valves can handle applicationsinvolving high built-up back pressure.

Crosby Series 800, Series 900 OMNI-TRIM®,and Series BP pressure relief valves arefurnished with a threaded cap over theadjusting bolt as a standard. Optional captypes and lifting levers are described below.

1. Standard Threaded Cap (Type A) Where no lifting lever is required.

2. Threaded Cap with Test Rod (Type B)Normally used to hold the pressure reliefvalve closed when the system is beinghydrostatically tested.

3. Packed Lifting Lever (Type D)For applications where periodic testing isdesirable. This is a sealed design forpressure integrity.

Note: ASME Boiler and Pressure Vessel Coderules require that a lifting lever must besupplied with the valve when the service is (1) air, (2) water at the valve inlet that exceeds140°F [60°C] excluding over pressure or reliefevents, or (3) steam.

4. Packed Lifting Lever with Test Rod (Type E) Same as Type D except furnishedwith a test rod.

caution: Test Rods should never betightened more than fingertight.Overtightening may damage internal parts.Moreover, a test rod should never be kept onthe valve during operation of the equipment.During normal operation the test rod isreplaced with cap plug and O-ring tomaintain tightness on the discharge side.

Style HE ISOFLEX®



IntroductionFormerly known as Style HE, Style HEISOFLEX® incorporates our latest seattightness design. Exceptional seat tightnessresults from an intensive engineeringproduct design analysis and upgradeprogram. For detailed discussion on thespecific improvements incorporated in theStyle HE ISOFLEX® design, and its “field-proven” results, please contact yourlocal Crosby Sales Representative.

Style HE ISOFLEX® safety valves are highpressure, high capacity reaction type valves,designed specifically for saturated steamservice on boiler drums having designpressures above 2000 psig [138 barg] up tocritical pressure. It incorporates the uniquepatented eductor control that permits thevalve to attain full capacity lift at a pressure3% above popping pressure in accordancewith the requirements of Section I of theASME Boiler and Pressure Vessel Code.

Low Friction Set Point AdjustmentSprings on drum safety valves, of necessity,have very high preloads. A thrust bearing (25)between the adjusting bolt (26) and topspring washer (21) makes set pointadjustments precise and keeps frictiontorque low. The valve seats are protectedfrom damage during set point adjustment bylugs on the upper spring washer (21). Thelugs engage the bonnet (17) to preventrotation of the spring (20), spindle (12) anddisc insert (5).

Precise Popping and Blowdown ActionThe principle feature of the design is a dual-stage, controlled flow passage formedby the eductor (9), disc holder (6) and theadjustable guide ring (10).

The controlled flow passages co-act with theapertured guide ring to control the flow ofsteam to a chamber above the disc holder(6). Changes in chamber pressure plus theaction of other internal parts assure fullopening without warn and also assist inpositive blowdown. By adjusting the guidering, blowdown between 2% and 4% isobtained as required by Section I of the ASMECode. The adjustable nozzle ring (3) ensuresaccurate, warn-free and sharp pop action onopening.

Tight Shut-off with ISOFLEX® DesignStyle HE ISOFLEX® valve seals off tight. Theseat-level loading of the spindle (12) on thedisc insert (5) ensures uniform seat-loading.The seating region of the ISOFLEX® discinsert is recessed for pressure loading andtemperature equalization ensuring maximumseat tightness.

OperationA typical valve operating cycle is as follows:as pressure in the boiler increases to thesafety valve set point, the valve will pop open.After the valve opens, steam passes througha series of flow passages (A) and (B) whichcontrol the pressure developed in chambers(C) and (D), the excess steam exhaustingthrough guide ring openings (E) to the valvebody bowl (F).

As pressure in the boiler decays, the dynamicforces on the lower face of the disc holderassembly are reduced and the safety valvedisc begins to close. Assisted by pressure inchambers (C) and (D), the valve at this pointcloses sharply and tightly.

The relieving capacities of Style HCIISOFLEX® have been determined by capacitycertification tests conducted in accordancewith ASME Code, Section I rules and arecertified by the National Board of Boiler andPressure Vessel Inspectors. Certifiedcapacities are listed in the National Boardpublication, “Pressure Relief DeviceCertifications.”

High CapacityThe adjustable nozzle and guide rings (3 and 12) utilize the reactive and expansive forces of the flowing steam toprovide full capacity lift. Valve capacity isdetermined by the nozzle (1B) throat areaalone. With high capacity valves, positiveoverpressure protection is achieved with thefewest number of valves.

Tight Shut-offThe Style HCI ISOFLEX® Safety Valve sealsoff tight. The seating region of the ISOFLEX®disc insert (5) is recessed for pressure andtemperature equalization ensuring that theseats remain flat in service.

Two Ring DesignBlowdown control is precise with twoadjustable rings (3 and 12) - one each on the nozzle (1B or 2) and guide (11).Blowdown may be adjusted from 2 to 4%under operating conditions.

Precise Popping PointClose machining tolerances assure that thedisc insert (5) is precisely centered, andspecial guide and disc/disc holder materialsand surface finishes ensure low frictionguiding at all temperatures. Springspecifications are held to rigid tolerances,and stresses are kept within lowest practicallimits. The open bonnet exposes the spring toatmosphere, minimizing thermal effects. Thevalves open precisely at their established setpressure, even after repeated cycling.

Style HCI-R ISOFLEX®

Restricted Lift Feature Crosby offers an optional restricted liftfeature with its HCI ISOFLEX® SafetyValves (HCI-R). The restricted lift option isavailable on all HCI ISOFLEX® valve sizes,with either flanged or weld endconnections.

The capacities for Style HCI-R SafetyValves with the restricted lift option adjustfrom 100% to 30% of full rated capacity.Restricted capacity = (% of restricted lift) x(ASME rated capacity).

• Eliminating over-capacity permits an economic distribution of relievingcapacity between the drum andsuperheater valves, often resulting in a smaller superheater safety valveselection.

• Reduces reaction forces.

• Standardization of valve sizes allowsboiler manufacturers to build standardboilers.

• Quality and performance assured viatamper-proof installation (preventserroneous changes in capacity).

Introduction Crosby’s Style HSJ is a full nozzle reactiontype safety valve designed for saturated andsuperheated steam service. The valvecombines the technical excellence ofCrosby’s field proven Styles HS and JOSdesigns and are in accordance withrequirements of the ASME Boiler andPressure Vessel Code, Section I, PowerBoilers, and Section VIII, Unfired PressureVessels. Discharge capacities are certified bythe National Board of Boiler and PressureVessel Inspectors.

The Style HSJ safety valves arerecommended for use on Boilers at designpressure from 15-600 psig [1-41 barg]. ForEconomizer, Dowtherm® and Section VIIIapplications, the HSJ Pressure Relief valvesare designed for pressures to 2700 psig [186barg] and temperatures to 1000°F [538°C]. This valve line is available in sizes 11/2 F 2 to6 Q 8 with ANSI Cl 150, 300, 600, 900, 1500and 2500 inlet flanges.

High Performance The adjustable nozzle ring (3) and guide ring(9) utilize the reactive and expansive forces offlowing steam to provide full lift. Valvecapacity is governed by the nozzle throat areaalone. With high capacity valves, positiveoverpressure protection is achieved with thefewest number of valves.

Two-Ring DesignPrecise blowdown control is provided by theadjustable two-ring design. Blowdown maybe conveniently adjusted while the valve isinstalled in the system.

Shut Tight - Stay Tight Style HSJ valves shut off tight. Years ofapplication engineering have resulted in aFLEXI-DISC® (6) which is recessed forpressure and temperature equalizationensuring a flat, tight seal that is capable ofcontaining system pressure at 94+% of thevalve’s set pressure.

Precise Popping Point Centering of the disc (6) through the lowfriction guide (8) ensures that Crosby’s HSJSafety Valves open precisely at set pressure,even after repeated cycling.

Options Closed and open bonnets are available for each valve size up to the maximumpressure rating (see pages 22-23). Closedbonnet valves, equipped with bonnet vents,are recommended for ASME Section VIIIoutdoor service. For ASME Code Section I,outdoor applications, select an open bonnetwith weatherhood. When ordering, specifyopen or closed bonnet. Note: Bonnet vents areessential for proper valve operation andshould not be plugged (except for Style HSJ-DOW shown below).

Demands upon a Dowtherm® vaporizersafety relief valve are severe. Temperaturesare high and absolute seat tightness isrequired. For Dowtherm® service, specifysafety relief valve Style HSJ-DOW. This valveis furnished with an unvented closed bonnetand Type A screwed cap. It also has an alloysteel spring for high operating temperatures.Style HSJ-DOW meets the requirements ofthe ASME Boiler and Pressure Vessel Code,Section I, Part PVG, “Requirements forOrganic Fluid Vaporizer Generators.” Fororganic fluid capacities, consult your salesrepresentative.

Note: For steam capacities at 10% overpressure up to absolute pressure of 1500 psia, multiply the capacity from above table by ratio 1.10p + 14.7 where p is set pressure (psig).1.03p + 14.7

* Capacity formula:

W = (51.5 x AP x K)For pressures over 1500 psig and upto 3200 psig the value of W shall bemultiplied by

0.1906P - 10000.2292P - 1061

Where:

W = Rated capacity, lbs/hr.

P = (1.03 x set pressure) + 14.7= absolute pressure, psia

K = 0.878 = average coefficient of discharge

A = nozzle throat (orifice) area, sq.in.

Superheat Correction Factor -Ksh



ASME Section I safety valves are devicesdesigned to protect power boilers during anoverpressure event. The proper sizing, selection,manufacturing, assembly, testing andmaintenance are all critical to obtain optimumprotection.ASME Code Section I1. Boilers-Safety Valve requirements (PG-67)a. Boilers having more than 500 sq. ft. ofbare tube and boilers having combinedbare tube and extended water heatingsurfaces exceeding 500 sq. ft. as well as adesign steam generating capacityexceeding 4000 lb/hr [1814 kg/hr] musthave two or more safety valves. If only twosafety valves are used, the relievingcapacity of the smaller must not be lessthan 50% of that of the larger, so if onlytwo valves are used, select valves so thateach will relieve approximately half of thetotal boiler capacity.

2. Superheater Safety Valve Requirements (PG-68)a. Boilers having attached superheatersmust have at least one valve on thesuperheater. The valves on the drum mustbe large enough to relieve at least 75% ofthe total boiler capacity. It is good practiceto size the superheater valve to relieveapproximately 20% of the total boilercapacity to protect the tubes againstoverheating.

3. Reheater Safety Valve Requirements (PG-68)a. Boilers having reheaters must have atleast one safety valve on the reheateroutlet capable of relieving a minimum of15% of the flow through the reheater. Theremainder of the flow through thereheater may be discharged by safetyvalves on the reheater inlet.

4. Economizer Safety Relief ValvesRequirements (PG-67) (Closed bonnet typevalve)a. Any economizer which may be shut offfrom the boiler, thereby permitting theeconomizer to become a fired pressurevessel, shall have one or more safetyrelief valves with a total dischargecapacity, in lbs/hr, calculated from themaximum expected heat absorption inBTU/hr, as determined by theManufacturer, divided by 1000. SafetyRelief valves in hot water service are moresusceptible to damage and subsequentleakage than safety valves relieving steam.It is recommended that the maximumallowable working pressure of the boilerand the safety relief valve setting beselected substantially higher than thedesired operating pressure so as tominimize the times the safety valve mustlift.

5. Organic Fluid Vaporizer Safety ValveRequirements (Dowtherm Service, PVG-12)a. Safety valves shall be totally enclosed andshall not discharge to atmosphere, exceptthrough an escape pipe that will carrysuch vapors to a safe point of dischargeoutside of the building. The safety valve shall not have a liftinglever and valve body drains are notmandatory. A rupture disc may beinstalled between the safety valve and thevaporizer.

The required minimum safety valve relievingcapacity shall be determined from the formula.

C x H x 0.75W =

hwhere:h = latent heat of heat transfer fluid at

relieving pressure, Btu/lbW = weight of organic fluid vapor

generated per hour, lbC = maximum total weight or volume of

fuel burned per hour, lb or cu ftH = heat of combustion of fuel, Btu/lb or

Btu/cu ftThe sum of the safety valve capacities markedon the valves shall be equal to or greater thanW.6. Sample Calculations - Boiler Set SizingBoiler Specifications:Total steam generation: 1,450,000 lbs/hr.Design Pressure (MAWP): 3000 psigDrum Operating Pressure: 2835 psigS.H. Outlet Temperature: 1000°FS.H. Outlet Operating Pressure: 2680 psig

The superheater valve should relieve between15% and 20% of the total generation capacity,or 217,500 lbs/hr. to 290,000 lbs/hr.The superheater safety valve should be set tooperate before the low set drum valve.To determine superheater safety valve setpressure:2835 psig – 2680 psig = 155 psiDrum Superheater SH PressureOperating Outlet DropPressure Operating

** Can round set pressure up or down for evennumber.

The Superheat Correction Factor Ksh is foundon page 40. First convert Set Pressure Gaugeto Flowing Pressure Absolute by:

2825 psig x 1.03 + 14.7 = 2924.45 psia.At 2924.45 psia and 1000F the Ksh = 0.711

To relieve 217,500 lbs/hr. superheated steam,the superheater valve must relieve217,500/0.711 = 305,907 lb/hr. saturatedsteam.From Capacity Table, page 34, a K2 orificevalve set at 2825 psig will relieve 381,228lbs/hr. saturated steam or 381,228 x 0.711 =271,053 lbs/hr. superheated steam.A 21/2 x K2 x 6 HCI-98W with welded inlet isrequired.The balance of steam to be relieved by drumvalves; 1,450,000 -271,053 = 1,178,947 lbs/hr. (Drumvalves must relieve a minimum of 75% totalboiler cap).Low set drum valve must = 3000 psig (MAWP-PG-67.3).High set drum valve = 1.03 x 3000 = 3090 psig (PG-67.2).The average set pressure for drum valve = 3045 psig.From Capacity Table, page 34, at 3045 psig;two M orifice valves will discharge 604,733 x 2+ 1,209,466 lbs/hr. Selection should be basedon price comparison and also on using asmany valves as practical of the same size. Inthis case, two M orifice valves should be used.Actual valve capacities from Capacity Table,page 34:1st drum valve, 3 x M x 6 HE-96W

271,053 lbs/hr. (18.7%)Total safety valve capacity:

1,481,028 (102%)Rechecking, the drum valves relieve 83.4% oftotal boiler capacity (complying with ASMECode requirement that drum valves relieve atleast 75% of boiler capacity). Superheater valverelieves 18.7% of total boiler capacity — withinthe desirable range of 15% to 20% of totalboiler capacity.

Total Outlet Reaction Force - lbs (Styles HE, HCI, HSJ) Total Resultant Force at Outlet Elbow*The figure below shows a safety valve openand discharging at full capacity, with a 90°outlet elbow. The horizontal reaction force(Fh) is balanced by the force of dischargingsteam acting on the 90° elbow.

The vertical force (Fv) at the 90° elbow is unbalanced and exerts a bending momenton the valve. The vertical force (Fv) is theresultant of the reaction due to velocity andthe static pressure of the steam acting on thearea of the elbow when the valve is open anddischarging.

The basic equation for this is:

Fv = WV + (APe)gc

Where:

Fv = Vertical forceW = Flow in lbs./sec.V = Velocity, ft./secA = Area of outlet, sq. in.Pe = Static pressure in outlet elbow,

psiggc = Gravitational Constant

Drip Pan Elbows For optimum safety valve performance, discharge piping should be supportedindependently of the valve. This can best be accomplished by installing a slipjoint arrangement at the inlet to the riser pipe, using a drip pan elbow.

The riser should be sized sufficiently larger than the slip joint to provideclearance during expansion of the boiler, and should be located with enoughclearance at the lower end to prevent “bottoming” on the drip pan.

Drain lines should be installed from the discharge elbow and the safety valvebody, and piped separately from any other drain or vent line. The size of thedrip pan elbow should be at least equal to that of the safety valve outlet size.

The Flanged Model EFS Drip Pan Elbow should be used without anyintermediary connection.

Weatherhoods Safety valves for outdoor installations shouldbe supplied with weatherhoods to protect the exposed spring and upperstructure from weather and thermal effects.Weatherhoods are available for all Crosby Series H valves. Contact your localsales representative.

Reseating Machines Crosby reseating machines will remachinethe nozzle seats in place without removingthe safety valve from the installation. Formcutters are used to cut a new seat to exactdimensions. Reseating machines, cutters andauxiliary equipment may be rented orpurchased. Contact your local salesrepresentative.

Jacking Devices When a safety valve is to be disassembledand it is desired to retain springcompression, i.e., the set pressure, amechanical or hydraulic jacking device maybe used. Jacking devices are used to lift thelower spring washer sufficiently to allow thedisc insert to lift clear of the nozzle(permitting the entire bonnet assembly to beremoved). Jacking devices may be rented orpurchased. Contact your local salesrepresentative.

Air (ASPD) and Hydraulic (HSPD) SetPressure DevicesThe set pressure of safety valves may bedetermined without raising system pressureto the popping pressure of the valves by usinga Crosby set pressure device which may berented or purchased.

The apparatus consists of a lifting devicemounted on the bonnet and connected to thespindle of the safety valve. The differentialforce, required to open the safety valve whenthe system (steam) pressure is less than thevalve set pressure, is applied by the operator. The differential force at which the valve opensis determined and the safety valve setpressure is calculated from thismeasurement. Contact your local salesrepresentative.

Ordering Information

Safety valves listed in this catalog are for steam service on steam generators, unfiredpressure vessels and pipe lines. To assist customers in selecting proper safety valves, Crosbywill recommend the most suitable safety valve, size and style. In order to do this, the followinginformation is required:



Safety valves are intended to open and closewithin a narrow pressure range; therefore,valve installations require careful andaccurate design both as to inlet anddischarge piping. The higher the operatingpressure and the greater the valve capacity,the more critical becomes the need forproper design of the installation. (ASME/ANSIPower Piping Code B31.1)

Inlet PipingSafety valves should always be mounted in avertical position directly on nozzles having a wellrounded approach that provides smooth,unobstructed flow from the vessel or line to thevalve. A safety valve should NEVER beinstalled on a nozzle having an insidediameter smaller than the inlet connectionto the valve, or on excessively long nozzles.The pressure drop occurring in the inlet pipingbetween the valve and pressure source shouldbe computed at actual flow of the valve. It is wellto remember that the ASME Boiler Code, SectionI rating for safety valves is only 90% of the actualflow. The safety valve or safety relief valve(s) shallbe connected to the boiler independent of anyother connection, and attached as close aspossible to the boiler or the normal steam flowpath without any unnecessary intervening pipeor fitting. Such intervening pipe or fitting shallnot be longer than the face-to-face dimension ofthe corresponding tee fitting of the samediameter and pressure under the applicableAmerican National Standard. The wallthickness of the inlet piping must be heavyenough to resist bending moments due toreaction when the valve discharges.Ask for paper by J.R. Zahorsky entitled,“Degradation of Pressure Relief ValvePerformance caused by Inlet PipingConfiguration.”

Outlet Reaction ForcesThe forces created by the steam dischargingfrom a safety valve will impose a reactive loadon the inlet of the valve, the mounting nozzle,and the adjacent supporting vessel. Theprecise nature of the loading and theresulting stresses will depend on theconfiguration of the valve and the dischargepiping. This must be taken into considerationby those responsible for the installation ofthe safety valve and associated vessel orpiping.

Determination of Outlet Reaction Forces is theresponsibility of the designer of the vessel and/or piping.(See pages 46-49).

BoilersCrosby recommends that the absoluteminimum differential pressure, i.e., thepressure between the valve set pressure andoperating pressure, be not less than 5% toensure seat tightness.

Nozzles for safety valves on boiler steam drums must have inside diameters equal to the valve nominal size. Nominal diameter plus 1/2" or more isrecommended, particularly for valvesmounted off the center line of the drum.

HeadersOn superheaters and reheater headers, inletnozzle connections for safety valves should beas short as possible. It is desirable to usepiping nozzles having a rounded entrance andlarger ID than the valve nominal size.

This is often necessary to keep the inletpressure drop within limits. Such connectionsshould be away from turns or branches whichcan cause turbulence.

Pipe LinesWhere safety valves are installed to protect apiping system, as on the low pressure side of areducing valve or on a turbine bypass, the pipeor header must be of sufficient size tomaintain flow under the safety valve while it isdischarging. On a pressure reducing valveinstallation, the safety valves should be locatedat least eight pipe diameters downstream fromthe pressure reducing valve. Where nozzles areused, they must be as short as possible andpreferably one pipe size larger than the valveinlet. Nozzles must be designed tocounterbalance the reaction when the valvedischarges. Several smaller valves are betterthan one large valve, and the set pressure ofeach valve should be staggered within ASMEBoiler and Pressure Vessel Code limitations.

When safety valves are installed on a header or vertical riser, the connection should be as closeand as short as possible. The exit from the header or riser should be larger than the valve inlet,have a well rounded approach and a uniform reduction of diameter with no abrupt changes,preferably with a smooth, gradual taper (similar to a seamless reducing or Y fitting). The designshould also result in minimum pressure drop from the header or riser to the safety valve.

Pentair is an equalopportunity employer.

Discharge PipingThe discharge piping from safety valvesshould be equal in size to, or larger than,the nominal valve outlet and should be assimple and direct as possible.Connections with generous clearances arepreferred. The discharge pipe above thedrip pan should be sized adequately toavoid “blow back” of steam from aroundthe drip pan into the boiler room when thevalve is discharging. Where piping extendsto a considerable length, it may benecessary to increase the pipe size at theupper part of the stack.

Where flexible hose connections are usedin place of or in conjunction with drip pans,they must be of sufficient length andflexibility so as to absorb expansion andimpose no strains on the valve outlet whenthe pressure vessel is at normal operatingpressure.

Where solid piping must be used,expansion bends should be employed toaccomplish the same purpose.

Discharge ManifoldsDischarge manifold lines are satisfactory ifthe following “good practices” areobserved:

The area of the manifold should be equal toor larger than the areas leading into it.“Stepping up” the size of the manifold ateach point where another valve dischargeline enters permits smoother flow thansimply sizing the manifold to the total arearequired.

The manifold should be independentlysupported and not on the valves.

The same precautions should be observedin providing drip pans, flexible connectionsand expansion bends on the individualdischarge valve lines leading into themanifold.

The manifold should be adequatelyanchored to prevent it from swaying andadequate drains should be provided.

The discharge lines should be led into themanifold at an angle of 45 degrees (less ifpossible) to the direction of the steam flow.

The manifold should be checked forpossible back pressure which might causesteam “blow back” out of individual drippans. If closed systems are used, backpressure in the manifold resulting whenone valve discharges can affect the poppingpoint and the performance of other valvesconnected to the same system.

Note: All discharge piping in thedischarge system must be vented to asafe disposal area to prevent personnelinjury when the valve discharges.Design considerations are included in thefollowing articles: “Steam Flow ThroughSafety Valve Vent Pipes” by H.E.Brandmaier and M.E. Knebel (December1975), “Analysis of Power Plant Safety andRelief Valve Vent Stacks” by G.S. Liao(November 1974), and “Safety Valve VentPipe Sizing for Open Discharge Systems” byJ.W. Sale (June 1979). The latter papers areASME publications.

DrainsProvisions for drains are located in thevalve bodies and should be piped to adrainage system to remove condensate

from the valve bodies. Separate drains arerecommended to drain the drip pan and oncertain types of installations additionaldrainage from the discharge piping may beprovided. This is especially true in marineinstallations where it is essential that themain atmospheric exhaust stack beprovided with a drain pocket at the lowestpoint, and that a separate drain line becarried from this pocket to the bilge.

Note: All drains and piping in thedischarge system must be piped to a safedisposal area to prevent possiblepersonnel injury when the valvedischarges.

Hydrostatic Testing of BoilersHydrostatic test plugs are recommended byCrosby for use on welded inlet valves. If flanged inlet valves are to be installed, werecommend that the hydrostatic test becompleted prior to installing the safetyvalve by blanking off the boiler opening. Ahydrostatic test plug is supplied for allwelded inlet valves. Hydrostatic test plugscan be supplied on request for any flangedinlet safety valve.

Technical literature is provided for CrosbySeries H valves which describes thespecific type and use of hydrostatic testequipment available.

IntroductionCrosby Style HSL is a full nozzle reactiontype safety valve designed for saturated andsuperheated steam service. The design issuitable for set pressures to 725 psig [50barg] and temperatures to 1000°F [538°C],with high capacities, two choices of inletflange ratings and a simplicity of design tofacilitate ease of maintenance.The HSL design meets the requirements ofASME Code Section I, Power Boilers andrelieving capacities are certified by theNational Board of Boiler & Pressure VesselInspectors. Style HSL may also be used insteam service applications covered by ASMECode Section VIII requirements.

Features• FLEXI-DISC seat design: recessed forpressure and temperature equalization.Ensures a flat and tight seal.

• High coefficient of discharge: results inthe most economical valve selection.

• Replaceable full nozzle design:facilitates ease of maintenance andlonger service life. Nozzle removalrequires no special tools.

• Seat tightness: FLEXI-DISC seat capableof containing system pressure at 94% ofset pressure. Standard seat tightnesstesting conducted at 93% of set pressure.

• Single bonnet design: allows setpressure changes without the need tochange-out any components besides thespring.

• Back pressure limit: 27.5% of setpressure



The adjustable Nozzle Ring and Guide Ring(Figure 1) utilize the reactive and expansiveforces of flowing steam to provide full lift.With a high K x A, positive overpressureprotection is achieved with the fewest numberof valves.

Precise blowdown control is provided by theadjustable two-ring design. Blowdown may beadjusted while the valve is installed in thesystem.

Style HSL safety valves incorporate theCrosby FLEXI-DISC design which is recessedfor pressure and temperature equalizationensuring a flat, tight seal capable ofcontaining system pressure at 94% of thevalve set pressure.

Centering of the disc through the low frictionguide ensures the HSL open precisely at setpressure, even after repeated cycling.

The single bonnet design utilized in both inletflange ratings allows set pressure changeswithout the need to change-out anycomponents other than the spring. The setpressure range for Cl300# valves is 15 psig[1.034 barg] to 330 psig [22.75 barg] and 15psig [1.034 barg] to 725 psig [50 barg] forCl600#.

The back pressure limit of the HSL is 27.5%maximum. Blowdown may increase slightlywhen back pressure is present.

Style HSL safety valves are available withoptional test gags, weatherhoods for outdoorapplications, and Class 150# Drip PanElbows. Ring type joint inlet connection isalso available.

The entire HSL range of F thru Q orifices uses a full nozzle design (Figure 1) tofacilitate removal and ease of maintenancecompared to semi-nozzle designs. (foradditional information refer to instructionmanual #IS-V3187)

Notes:1. For steam capacities at 10% overpressure, multiply the capacity from the above table by

the ratio

1.10p + 14.7

1.03p + 14.7

where “p” is set pressure (psig).

2. For superheated steam, multiply the saturated steam capacities by SuperheatCorrection Factor Ksh on page 12.

Capacity formula:W = (51.5 x AP x K)

WhereW = Rated capacity, lbs/hr.P = (1.03 x set pressure) + 14.7 = absolute pressure, psiaK = 0.869 = average coefficient of dischargeA = nozzle throat (orifice) area, sq. in.

Total Resultant Force at Outlet Elbow2

The figure (left) shows a safety valve open and dischargingat full capacity, with a 90° outlet elbow. The horizontalreaction force (Fh) is balanced by the force of dischargingsteam acting on the 90° elbow.

The vertical force (Fv) at the 90° elbow is unbalanced andexerts a bending moment on the valve. Vertical force (Fv)is the resultant of the reaction due to velocity and thestatic pressure of the steam acting on the area of theelbow when the valve is open and discharging.

Sizing ASME Section I Safety ValvesASME Section I safety valves are devices designed to protect powerboilers during an overpressure event. The proper sizing, selection,manufacturing, assembly, testing and maintenance are all critical toobtain optimum protection.

ASME Code Section I1. Boilers-Safety Valve Requirements (PG-67)Boilers having more than 500 sq ft of bare tube and boilers havingcombined bare tube and extended water heating surfacesexceeding 500 sq ft as well as a design steam generating capacityexceeding 4000 lb/hr. must have two or more safety valves. If onlytwo safety valves are used, the relieving capacity of the smallermust not be less than 50% of that of the larger, so if only twovalves are used, select valves so that each will relieveapproximately half of the total boiler capacity.

2. Superheater Safety Valve Requirements (PG-68)Boilers having attached superheaters must have at least onevalve on the superheater. The valves on the drum must be largeenough to relieve at 75% of the total boiler capacity. It is good practice to size the superheater valve to relieveapproximately 20% of the total boiler capacity to protect the tubesagainst overheating.

3. Reheater Safety Valve Requirements (PG-68)Boilers having reheaters must have at least one safety valve onthe reheater outlet capable of relieving a minimum of 15% of theflow through the reheater. The remainder of the flow through thereheater may be discharged by safety valves on the reheater inlet.

4. Sample Calculations - Boiler Set SizingBoiler Specifications:

Total steam generation 170,000 lb/hr.Design Pressure (MAWP) 500 psigDrum Operating Pressure 450 psigS. H. Outlet Temperature 550°FS. H. Outlet Operating Pressure 425 psig

The superheater valve should relieve between 15% and 20% of thetotal generation capacity, or 25,500 lbs/hr. to 34,000 lbs/hr.

The superheater safety valve should be set to operate before the lowset drum valve.

To determine superheater safety valve set pressure:

450 psig – 425 psig = 25 psi

(Drum Operating) (Superheater Outlet ) (SH Pressure)Pressure Operating Pressure Drop

500 psig – 25 psi - 15 psig1 = 460 psig(Design Pressure) (SH Pressure Drop) (Set Pressure2)

The Superheat Correction Factor Ksh is found on page 12. Firstconvert Set Pressure Gage to Flowing Pressure Absolute by:

460 psig x 1.03 + 14.7 = 488.5 psia At 488.5 psia and 550°F the Ksh = 0.945

To relieve 25,500 lbs/hr. superheated steam, the superheater valvemust relieve 25,500/0.945 = 26,984 lb/hr. saturated steam.

From Capacity Table, page 10, a J orifice valve set at 460 psig willrelieve 29,011 lbs/hr. saturated steam or 29,011 x 0.945 = 27,415lbs/hr. superheated steam.

A 11/2 J 21/2 HSL-46 is required.The balance of steam to be relieved by the drum valves; 170,000 -27,415 = 142,585 lbs/hr. (Drum valves must relieve a minimum of75% total boiler capacity).

Low set drum valve must set at 500 psig (MAWP-PG.67.3). High setdrum valve 1.03 x 500 = 515 psig (PG-67.2).

From Capacity Tables, page 10, at 500 psig; two “L” orifice valves willdischarge 75,077 x 2 - 150,154 lbs/hr.

Selection should be based on price comparison and also on usingas many valves as practical of the same size. In this case, two “L”orifice valves should be used.

Industry practice would be to use two (2) valves on the drum.Actual valve capacities from Capacity Table, page 10.1st drum valve, 21/2 L 4 HSL-46 500 psig - 75,077 lbs/hr.2nd drum valve, 21/2 L 4 HSL-46 515 psig - 77,266 lbs/hr.Total capacity drum valves: 152,343 lbs/hr. (89.6%)Capacity of superheater valve: 27,415 lbs/hr. (16.1%)Total safety valve capacity: 179,758 lbs/hr. (105.7%)Rechecking, the drum valves relieve 89.6% of total boiler capacity(complying with ASME Code requirement that drum valves relieve atleast 75% of boiler capacity). Superheater valve relieves 16.1% oftotal boiler capacity – within the desirable range of 15% to 20% oftotal boiler capacity.

Notes:1. The 15 psig subtracted from the superheater pressure drop is done to

ensure that the superheater safety valve opens before the low set drumsafety valve.

2. Can round set pressure up or down for even number.

SEAT DESIGN

Series JOS-E and JBS-E relief valves are available with flat metal-to-metal or soft seats. Their two-piece disc holder/disc insert construction provides thermal balancing assuring maximum seat tightness and meets the requirements of API Standard 527, ‘Seat tightness of pressure relief valves’.

Where system operating conditions permit, soft or elastomer O-ring seat construction is available as an option. This two-seat design (Figure 1) has a metal-to-metal seat located downstream of the soft seat. The O-ring is the primary seal. The flat metal-to-metal seat controls the compression of the O-ring and also serves as a secondary seal should the O-ring be damaged. Elastomeric O-ring soft seat valves are tightness tested at 95% of set pressure, exceeding the requirements of API Standard 527.

Standard O-ring materials include Viton®, Buna-N, EPR, TFE, silicone rubber and Kalrez® (see page 16). Other soft seat materials, their pressure and temperature limits are available on application.

DUAL CERTIFICATION

Series JLT pressure relief valves for liquid service were developed using our unique patented trim design. This contoured liquid trim design (Figure 2), with over 25 years of successful field experience, was patented prior to the issuance of ASME Code Section VIII requirements that became mandatory in 1985. The JLT trim offers a significant increase in capacity at 10% overpressure and, in many cases, results in selection of a smaller valve with an associated reduction in inlet and discharge piping costs. The JLT design is also capacity certified for gas and vapor service and can be applied in two-phase flow applications. The JLT design is a logical choice where the process fluid may be a liquid or gas depending on the overpressure condition.

BELLOWS AND TOP FLANGE

All standard JBS-E and JLTJBS-E valves feature a standard bellows and top flange (Figure 3) manufactured from Inconel® alloy 625, which is a fatigue-resistant material and provides improved corrosion resistance compared to 316L stainless steel. It is highly resistant to pitting, crevice corrosion and inter-granular attack. The standard bellows assembly threads onto the disc holder with a bellows tailpiece and gasket. A welded bellows attachment is available as an option.

BELLOWS CONVERTIBILITY

The flanged, spring operated pressure relief valve is designed and manufactured as a conventional valve and a balanced bellows valve. The conversion from conventional Series JOS-E or JLTJOS-E in sizes 1" D 2" through 8" T2 10" requires only the addition of a bellows assembly and bellows tail-piece gasket. No other parts are necessary.

CAP, LIFTING LEVER AND SPINDLE INTERCHANGEABILITY

All JOS-E and JBS-E relief valves (except restricted height caps) use a threaded spindle and drilled and tapped bonnet which permits easy cap or lifting lever conversions, with maximum standardization and interchangeability of parts. In addition, standard cap and lifting lever designs can be used with in-line test devices.

FIGURE 4EASE OF MAINTENANCE AND COMPONENT INTERCHANGEABILITY

The JOS-E and JBS-E’s disc insert retention, disc holder and nozzle ring have been engineered to ensure ease of maintenance, minimize spare parts and provide a high degree of component part interchangeability (Figure 4).

The disc insert is held securely in place with a compressible retention clip. A ‘universal’ disc holder allows simple and cost effective conversions from conventional to balanced bellows design and enables cost-effective bellows replacement.

The nozzle ring encloses the adjustment slot at the bottom of the ring giving a rugged, durable design.

SERIES JBS-E/JLTJBS-E PRODUCT OVERVIEW

Series JBS-E and JLTJBS-E pressure relief valves incorporate a bellows which is balanced to minimize the effects of variable back pressure on valve set pressure and can also handle applications involving high built-up back pressure.

Additionally, the bellows serves to isolate the guide, spindle, spring and other parts contained in the bonnet chamber from corrosive fluids or media such as a highly viscous fluid or slurry which could render the relief valve inoperative.

Their exceptionally rugged design features a high guiding surface ratio and corrosion resistant trim.

For liquid service applications, Series JLTJBS-E provides stable operating performance using our industry-recognized patented liquid trim design, which allows the valve to achieve full lift at 10% overpressure without valve chatter.

SERIES JLTJOS-E/JLTJBS-E LIQUID TRIM PRESSURE RELIEF VALVES

Series JLTJOS-E and JLTJBS-E pressure relief valves for liquid service were developed using our unique patented contoured trim design (Figure 5). The JLT trim offers a significant increase in capacity at 10% overpressure and in many cases, results in selection of a smaller valve with an associated reduction in inlet and discharge piping costs. It provides smooth and stable valve operation on liquid service applications.

OPERATION

When system pressure reaches the specified set pressure, a small steady stream of fluid begins to flow from the valve. Valve disc lift at this pressure is minimal.

As the system pressure increases into the range of 3% to 5% overpressure, the valve then opens with a pop type lift to the full lift position. At 10% overpressure, the JLT valve will have attained full lift and be flowing an amount equal to or greater than the rated capacity (Figure 6).

As the system pressure begins to drop, flow through the valve decreases until the valve reseats with a clean positive closing action.

The JLT design is also capacity certified for gas and vapor service and can be applied in two-phase flow applications.

SERIES JBSBP-E AND JLTJBSBP-E BALANCED BELLOWS VALVES WITH SUPPLEMENTARY BACK PRESSURE BALANCING PISTON

Series JBSBP-E and JLTJBSBP-E are a modification to the standard bellows pressure relief valves which have been designed and tested in collaboration with engineers of one of the world’s leading petroleum companies. This adaptation provides additional assurance of safe performance in the event of bellows failure on installations with discharge manifold systems where constant or variable back pressures are present.

With the standard bellows pressure relief valve, if the bellows is broken or ruptured, the valve will perform in the manner of a standard valve without bellows. Introduction of the supplementary back pressure balancing piston assures full performance characteristics of the valve until necessary replacement of the bellows can be made, affording double protection.

Unless compensated for, the effects of back pressure may cause (1) a change in the opening pressure (2) a decrease in valve capacity and (3) valve performance to become unstable at higher back pressure.

Use of the bellows valve with supplementary balancing piston maintains the balancing effect even after bellows failure enabling the valve to function in essentially the same manner as with the bellows intact. However, the bonnet of the valve must be vented to ensure proper valve functioning. The vent also serves as a ‘tell-tale’ in case of a ruptured or broken bellows.

DesignThe auxiliary balancing piston is incorporated in the basic bellows valve, modified to include the piston (5B) and the cylinder (17) which is part of the disc holder.The guiding clearances are held to a minimum and, in addition, grooves in the piston form a labyrinth seal to reduce flow between the piston and cylinder. In the event of a bellows failure, the leakage of fluid to atmosphere is kept to a minimum.

CapsStyles JOS-E/JBS-E/JLT pressure relief valves are furnished with a closed bonnet and screwed cap over the adjusting bolt. The following types of top construction are available, except where indicated otherwise:

Screwed cap (Type J standard) - where no lifting lever is required.Bolted cap (Type L) - where no lifting lever is required. Available to special order.

Lifting leversASME Code Section VIII requires that a lifting lever must be supplied with the valve when the service is: (1) air (2) water at the valve inlet that exceeds 140°F (60°C), excluding overpressure or relief events or (3) steam.

Regular (Type C) - for steam and air service where the valve cap is not required to be tight on the discharge side and where conditions dictate a requirement for periodic testing. Regular lifting levers may be furnished with a supplementary gagging device on special order (designated as Type T).

Packed (Type D) - For services where tightness on the discharge side is necessary and where conditions dictate a requirement for periodic testing. Also recommended for hot water services.

ASME Code Section VIII requirements for lifting levers: The omission of the lifting lever is permitted under Code Case 2203. However, Pentair Valves & Controls requires that orders for relief valves intended for steam, air or water over 140°F without lifting levers must indicate that the valves are specified in accordance with Code Case 2203. The buyer is responsible for obtaining jurisdictional approval for use of this Code Case.

Test rodsTypes K, E or M - valves with screwed caps, packed lifting levers or bolted caps can be fitted to accommodate test rods which will hold the valve closed when the equipment on which they are installed is hydrostatically tested.

Type J screwed cap changes to Type K with test rod. Type D packed lifting lever changes to Type E with test rod.

Type L bolted cap changes to Type M with test rod.

Height restricted applicationsFor applications where there are height restrictions, cap Types A, B, G and H are available.

CAUTIONTest rods should never be tightened more than finger-tight as over-tightening may damage internal parts. Also, a test rod should never be kept on the valve during operation of the equipment. During normal operation the test rod is replaced with a cap plug and gasket to maintain tightness on the discharge side.

FEATURES

• Geometrically designed body and bonnet eliminates the need for multiple, smaller orifice cast steel API Standard 526 pressure relief valves.

• Provides significant weight reduction when compared to multiple smaller orifice PRVs.

• Significantly reduces inlet and discharge piping costs.

• Reduced downtime and maintenance.• Fewer spare parts required.• Specific inlet/outlet flange configurations and

combinations available with unique center-to-face dimensions to meet existing systems.

• Forged body standard construction increases choice of materials available for harsh or corrosive service applications.

• Suitable for back pressure applications considerably beyond CI 300 service.

• Reliable and field proven design.

SERIES JOS-E-B/JBS-E-B PRODUCT OVERVIEW

Series JOS-E-B/JBS-E-B BlockBody valves provide greater capacity and can be set at pressures and temperatures significantly higher than the traditional design cast steel API Standard 526 relief valves. One single BlockBody installation has satisfied the capacity of twelve smaller valves.

The BlockBody design also adds significantly to the scope of materials that can be provided in accordance with ASME Code Section VIII by adding a wide array of wrought materials. Utilizing the BlockBody design, higher material integrity is offered which can minimize non-destructive examination (NDE) requirements.

BlockBody relief valves can be designed to unconventional sizes which can be an advantage when retrofitting to existing systems. Pressure relief valve outlet sizes can be increased beyond API standards to eliminate outlet piping reducers and mitigate built-up back pressure in the downstream piping.
