Safety Valves protect plants of all kinds from impermissible overpressure. They prevent damage to persons, the

environment and investments. As the last link in the safety chain, their perfect function must be ensured. The requirements

for development, design, production and quality management are correspondingly high.

Only comprehensive tests and trials can ensure that Safety Valves will always function perfectly, even under extreme service

conditions. Since the inception, FAINGER LESER has been operating micro processor based test lab. for determining the

function and characteristics of Valves. Critical components are machined on CNCs to accomplish the demanding

requirements placed by the International standards like DIN 3320, ISO 4126, ASME Sec. VIII etc.

FAINGER LESER VALVES (P.) LTD., a 100% owned subsidiary of M/s. LESER GmbH & Co. KG, Germany, manufactures

Safety & Relief Valves as per M/s. LESER Global Standard. They are approved by various International Agencies like TUV,

ASME etc. The Valves produced by FAINGER LESER are periodically retested at LESER & ASME certified test laboratory in

Germany.

1/01FAINGER LESER 2011

It has been always our endeavour to supply Safety & Relief Valves with the advanced manufacturing & testing techniques.

In this regard, we take pleasure to state that we are an ISO 9001:2000 certified company and also approved by both

statutory inspection agencies such as IBR, CCoE etc. and various Third Party inspection agencies.

We have manufactured & supplied so far over the past 16 years in excess of 50,000 Safety & Relief Valves to various user

industries for different applications in India & abroad.

CNC machines are also employed in the machine shop to ensure precision & accuracy required for the manufacture of

Safety & Relief Valves of the highest quality.

The microprocessor operated flow characteristic testing facility is used where required to ensure valve operating

performance & relieving capacity with air as the test medium.

The main ADVANTAGES of FAINGER LESER Valves are:

Universal, without changing trim applicable for steam/gas or liquid service, simple and user friendly in

construction.

No hassles of adjusting complicated Blowdown rings, because of fixed Blowdown type.

Blowdown, in general not exceeding the limits of valves with adjusting ring(s).

Higher capacity possible per size; for smaller API/ASME capacities lift stopper is used.

Spring loaded valve as a standard for pressures as low as 0.15 bar g.

Valve capacity & performance test, in-house by computer controlled test facility within its range.

1. Safety Valves with Stainless Steel Bellows

There are two reasons for the use of stainless steel bellows:

a) Bellows reliably seal the bonnet to the outlet chamber, protecting the guides, moving parts and the spring against

failure through action of the fluid, such as dirt, corrosion, impurities or temperature.

b) Stainless-steel bellows compensate for the effects of back pressure. They are so designed that the effective area of the

bellows is equivalent to that of the seating area.

Stainless-steel bellows must be used when built-up back pressure exceeds 15% of set pressure. Stainless steel bellows

can be used for back pressure up to a maximum of 35% of the set pressure.

The stainless-steel balanced bellows inherent stiffness affects set and function performance. The min. set pressure is

also dependent on the nominal dia. (DN) chosen. Depending on the set pressure, either single or double-walled

stainless steel bellows (standard) are used. A shield may also have to be installed if the unit is subjected to a

particularly high level of stress, such as abrasive fluids, flow effects, etc.

A BSP/NPT control thread is fitted into the bonnet to

monitor the efficiency of the bellows. A discharge pipe can

be attached to the threaded drain, in the event that

provisions have to be made for a safe discharge of fluids in

special cases e.g. aggressive or toxic fluids.

The design height of the safety valve is altered if the

stainless steel bellows are installed.

2. Safety Valves with Heating Jacket

Safety Valve can be fitted with a heating jacket for special applications. Areas of application are systems to be protected from

media, which are viscous, sticky or have tendency to crystallize out of solution.

In case of flanged Safety Valves without stainless steel bellows, only the bodies are fitted with a heating jacket. The heating

connections for these Safety Valves shall be NPT female or ANSI 150 # RF.

Safety Valves with stainless steel bellows

For Safety Valves with stainless steel bellows, the bonnet spacer required to house the bellows is fitted with an additional

heating jacket. Both heating jackets are joined by a threaded pipe bend.

To protect the sliding parts and the spring against inadmissible influence of temperature an additional equipment will beo o

necessary for all flanged spring loaded valves if the fluid temperature is 400 C (752 F) and higher.

o o

If the temperature is higher than 450 C (842 F) stainless steel bellows should be provided as far as they are not fitted

already by reason of the back pressure ratio.

4. Safety Valves with Test Gag

5. Safety Valves with Lift Stopper

In order to allow the adjustment of each Safety Valve in a plant provided with several Safety Valves or to carry out a pressure test

above the allowable operating pressure a test gag is required. The test gag is fitted in the lever cover and exerts force on top of

the spindle. After testing the test gag shall be removed.

That Safety Valves are only available in standardized nominal diameters, the valve could in a given application be oversized. It

is therefore recommended to reduce the lift by means of a lift stopper, thus reducing the coefficient of discharge in addition.

Lift stoppers must allow a lift of at least 1 mm.

Instructions for the Treatment and Installation of

Pressure Relief Valves.

1. General Notes

Pressure Relief Valves are highly quality instruments which should

be handled with great care. To ensure the correct performance of

a pressure relief valve all parts are made with exact precision.

Only this precision ensures the correct functioning of the pressure

relief valves. Careless handling of the finished valve in

workshops, stores, during transportation or installation could

cause leakage or possibly permanent damage (also refer to API

Report Guide for inspection of refinery equipment, Chapt. XVI

Pressure Relieving Devices" Para 1603082 and 1603083).

The sealing surfaces have been ground and lapped with high

precision to ensure the required tightness. Even though the

surfaces are extremely hard, the seal can still be damaged. By all

means, one must take care to prevent impurities from entering

the valve during transportation, installation and operation.

When installing pressure relief valves with threaded connections,

use only metal seal washers. Seal materials such as hemp or

PTFE tape should not be used as this type of material can break

off and enter the valve causing it to leak.

If valves with open bonnets and/or levers are to be painted after

despatch from the factory, care must be taken to protect the

sliding parts. Otherwise the correct operation of the pressure

relief valve may be affected.

2. Transport Protection

The inlet and outlet of the pressure relief safety valves are

protected during transportation with plastic caps. These caps

should only be removed just before installing the valve.

The lifting lever of spring loaded pressure relief valves is secured

with a wire to the bonnet. This wire should be removed only after

installation. For testing the set pressure or tightness of the

pressure relief valve remove also this wire and take care that the

lever is not engaged with the spindle cap.

3. Installation/Assembly

3.1 General Notes

Spring loaded pressure relief valves should be installed

with the bonnet VERTICALLY UPWARDS.

Furthermore, pressure relief valves should be mounted

in such a way that no inadmissible static, dynamic or

thermal loads can be transmitted to the valve due to up

and downstream pipe work. If necessary, expansion

possibilities should be provided. Stresses by incorrect

mounting should be avoided.

3.2 Draining of Condensate

To prevent dirt and all kinds of impurities from the

pressure relief valve the drainage of discharge pipe and

pressure relief valve must be done via discharge pipe.

Therefore, FAINGER LESER pressure relief valves are not

normally provided with drain holes.

According to rules a drain hole of sufficient size must be

incorporated at the lowest point of pipe work. In all

cases the discharge pipe must first slope in a

downwards direction and fitted with a suitable size

drain hole before any bends are connected (refer to

sketch).

Exception:

In special cases, for instance on board of ships an optional

drain hole may be recommended in the valve body as it may

be that pipe work drainage cannot be guaranteed at a lower

point than the valve. The standard drain hole which will then

be supplied by the factory is 1/4" BSP. But, by all means, the

discharge pipe must be drained too. In extreme cases this

hole can be drilled outside of our factory provided that

special care is taken to ensure that no damage is done to the

sealing surfaces.

All drainage pipes that have been connected must be free of

restriction and the ends easily seen. Care must be taken

when discharging any drainage to prevent injury to

personnel. For example on steam connect a suitable steam

trap.

Note!

When valves are supplied with a drain hole that is not going

to be used the plastic plug fitted in the hole must be removed

and replaced by a metal plug.

3.3 Mounting Brackets

For pressure relief valves with mounting brackets a

fastening possibility for the brackets should be provided

to withstand the forces of reaction when valve blows off.

The bracket holes can be drilled on request.

3.4 Insulation

In case any insulation of the pressure relief valve is

provided, the bonnet must be kept free to avoid

unacceptable heating up of the spring.

3.5 Inlet Pipe

The inlet pipe for pressure relief valves should be as

short as possible and should be so arranged, that when

the valve is in its fully open position the pressure drop

must not exceed 3% of set pressure, the edging at the

inlet pipe should be rounded off or at least be

chamfered.

If the calculation results in a higher than 3% pressure

drop of set pressure then the inlet pipe size must be

enlarged.

3.6 Discharge Pipes/Back Pressure

The discharge piping on vapours and gases should be

installed in an ascending direction, on liquids in an

inclined direction.

2/13

FL 441

2

FAINGER LESER 2011

The discharge pipework of all pressure relief valves

should be so arranged that the back pressure, which is

built up during blow off, does not exceed a max. 15% of

set pressure.

In case of higher back pressure, pressure relief valves

with pressure compensating metal bellows (balanced

type) shall be used. In case the back pressure is >0.15

times set pressure the capacity of the pressure relief

valves must be recalculated.

3.7 Pressure Relief Valves with bellows

Pressure relief valves with elastomer bellows (TRD 721)

as well as metal bellows have a vent hole in the bonnet.

When fitting pressure relief valve with a vent hole care

must be taken to prevent moisture from entering the

bonnet. However, fluid escaping from the vent hole

indicates that the bellows have failed. Repair is

required.

When pressure relief valves with bellows are used with

toxic or inflammable fluids, care must be taken to fit a

suitable vent pipe to provide safe venting. For this

purpose, the vent can be threaded 1/4" BSP female on

request.

4. Mode of Operation/Maintenance

The working pressure of the plant should be at least 5% below the

blow down pressure of the valve to enable a correct reseat. When

a slight leakage occurs, due to deposits between the sealing

surfaces, surfaces can be cleaned by operating the lifting lever

causing the valve to blow off.

The valve should be closed by sudden release of the lever. If this

procedure does not stop the leakage, the valve seals are

probably damaged. Repairs should be carried out at our

workshop or by a qualified person.

It is recommended and in Germany required by Rules to lift

manually the valve lifting lever from time to time in order to

prevent accumulation of deposits that will affect valve operation.

For steam generators, the following requirements are

established in the German Technical Rules for Steam Boilers TRD

601, edition 6.83, Section 6.

"Testing of pressure relief valves is required for plants operating

with demineralized water and for hot water generators at

intervals of at least 6 months, with the exception of power plants.

For other steam generators, the test interval should not exceed 4

weeks".

It is important to ensure that the lifting lever does not engage the

spindle cap after the lift operation. The lever must be deflected

towards the center line of the bonnet until the lifting fork is

disengaged.

For pressure relief valves with open bonnet, a drain groove is

provided in the guide flange. Whilst blowing, condensate

escaping through the clearance between guide disc and spindle

is drained through this groove.

According to DIN specification 4754, Oct. 74 Edition

"Explanations", Para 4.4 pressure relief valves represent the last

step in the line of protection for the vessel, and they should be

able to prevent excess pressure when all other automatic or pilot

operated checking instruments have failed. To guarantee this

function pressure relief valves require, like all other technical

equipment, regular service. How often a valve must be checked,

depends on the actual operating conditions, so that no general

indications can be given. Usually pressure relief valves operating

in a corrosive atmosphere or on laden fluids require service more

often than valves operating clean conditions. This also applies if

the pressure relief valve operates frequently causing a higher

wear out to the seat and disc.

Special consideration is required if conditions such as vibration

(to be avoided, if possible) pressure pulsation and/or a too small

difference between working and set pressure cannot be avoided.
