Valve Selection and Technical Data

For several decades Econosto Valves have set the standard in wide areas of industry. The majority of our Valves conform to recognized National / International Standards. Stringent quality control standards at all stages of manufacture assures our customers a high quality product. Advanced manufacturing techniques and equipment, a continuing programme of engineering research and product development, qualified engineers and several decades of experience in flow control are behind the quality and dependability built into every Econosto product.

This catalogue presents Econosto’s exclusive range of valves, instruments and other pipeline

products for the HVAC (Heating, Ventilation and Air Conditioning), Plumbing and Fire fighting industry. Information in this catalogue is complete and includes materials, construction, design standards, ratings, Original Images, dimensions and weight data.

Valve Selection Valves have been a simple device for turning on and shutting off flow. Valve design has kept pace with the progress made in the industry - the development in

piping techniques and the ever-growing list of fluids for various applications.

Progress in valve design provides the piping engineers with a huge variety of valve types, each with a unique feature for that application. It is important that the valve’s service characteristic's are suitable for the service requirements. It is important to know every detail viz : Working pressure, temperature, fluid or medium, volume of flow, corrosive elements, valve operating cycles etc. Econosto being one of world’s leading manufacturer’s of Valves helps our customers in valve selection as and when required. We provide complete solutions to our customers.

Hydrostatic & Shock Working Pressures Econosto Valves are suitable for liquid working pressures specified in the catalogue pages only when used in hydraulic installations in which shock is absent or negligible. Sudden closure of a valve in a hydraulic system causes the body of liquid, which may be moving at a rate in excess of 0.3metre (1 foot) per second to stop immediately. As liquids are incompressible, the sudden cessation of flow effects a rise in pressure considerably greater than the static working pressure; this pressure increased is termed ‘SHOCK’ and may, in some cases, be sufficient to cause valves or piping to fail. Pressure increase due to shock is not dependent upon the working pressure in the system but upon the velocity at which the liquid is flowing. This pressure surge or shock, severely limits design velocities. For example a pressure rise resulting from arrest of flow may be as high as 4 bar for each 0.3 metre (1 foot) per second initial velocity. For example, installations of 7 bar and 70 bar working pressures with the same initial velocity of 3 metre / second will be subject to the same increase in pressure (approx. 41 bar) due to the sudden closure of a valve. Shock generally prevails in lines equipped with check or quick closing valves, or in lines supplied by reciprocating pumps. It may also be produced to a lesser degree, by rapid closure of gate and globe valves. Therefore, care should be exercised when closing valves installed in liquid lines. When shock is likely to occur, the maximum shock pressure should be added to the working pressure of the line to determine working pressure of products in the line. Moreover hydraulic installations should be equipped with air chambers or other types of shock absorbers.

Valve Selection and Technical Data

For several decades Econosto Valves have set the standard in wide areas of industry. The majority of our Valves conform to recognized National / International Standards. Stringent quality control standards at all stages of manufacture assures our customers a high quality product. Advanced manufacturing techniques and equipment, a continuing programme of engineering research and product development, qualified engineers and several decades of experience in flow control are behind the quality and dependability built into every Econosto product.

This catalogue presents Econosto’s exclusive range of valves, instruments and other pipeline

products for the HVAC (Heating, Ventilation and Air Conditioning), Plumbing and Fire fighting industry. Information in this catalogue is complete and includes materials, construction, design standards, ratings, Original Images, dimensions and weight data.

Valve Selection Valves have been a simple device for turning on and shutting off flow. Valve design has kept pace with the progress made in the industry - the development in

piping techniques and the ever-growing list of fluids for various applications.

Progress in valve design provides the piping engineers with a huge variety of valve types, each with a unique feature for that application. It is important that the valve’s service characteristic's are suitable for the service requirements. It is important to know every detail viz : Working pressure, temperature, fluid or medium, volume of flow, corrosive elements, valve operating cycles etc. Econosto being one of world’s leading manufacturer’s of Valves helps our customers in valve selection as and when required. We provide complete solutions to our customers.

Hydrostatic & Shock Working Pressures Econosto Valves are suitable for liquid working pressures specified in the catalogue pages only when used in hydraulic installations in which shock is absent or negligible. Sudden closure of a valve in a hydraulic system causes the body of liquid, which may be moving at a rate in excess of 0.3metre (1 foot) per second to stop immediately. As liquids are incompressible, the sudden cessation of flow effects a rise in pressure considerably greater than the static working pressure; this pressure increased is termed ‘SHOCK’ and may, in some cases, be sufficient to cause valves or piping to fail. Pressure increase due to shock is not dependent upon the working pressure in the system but upon the velocity at which the liquid is flowing. This pressure surge or shock, severely limits design velocities. For example a pressure rise resulting from arrest of flow may be as high as 4 bar for each 0.3 metre (1 foot) per second initial velocity. For example, installations of 7 bar and 70 bar working pressures with the same initial velocity of 3 metre / second will be subject to the same increase in pressure (approx. 41 bar) due to the sudden closure of a valve. Shock generally prevails in lines equipped with check or quick closing valves, or in lines supplied by reciprocating pumps. It may also be produced to a lesser degree, by rapid closure of gate and globe valves. Therefore, care should be exercised when closing valves installed in liquid lines. When shock is likely to occur, the maximum shock pressure should be added to the working pressure of the line to determine working pressure of products in the line. Moreover hydraulic installations should be equipped with air chambers or other types of shock absorbers.

Pressure / Temperature Ratings

Nominal Pressure (PN): All the valves / other products in our catalogue are identified by their pressure ratings, which are generally in metric (PN) form. Econosto valves are designated by nominal pressure (PN) defined as the maximum permissible working pressure (in bar gauge) at 20 degree centigrade. Nominal pressure is shown by the letters PN followed by the appropriate reference number.

In this catalogue pressure / temperature ratings have been shown graphically, as this form is considered to be more meaningful than cold and hot limitations. In most of the cases the graphs have been based on rating tables from the relevant standards. The stated pressure / temperature ratings relate to the valve body & flanges and should be used only as a guide for comparison. For some valve types these ratings may be restricted due to the use of resilient seats, sealing materials etc.

Nominal Size (DN ): The prefix letters DN are used internationally to indicate the metric nominal size. It is a numerical designation of size which is common to all components in a piping system other than components designated by outside diameter or by thread size. It is a convenient round number for reference purposes and is only loosely related to manufacturing dimensions. Nominal size is designated by the letters ‘DN’ followed by a number.

A comparison of imperial and metric nominal sizes is shown below : Inches 1/8 1/4 3/8 1/2 3/4 1 1 1/4 1 1/2 2 2 1/2 3 4 DN 6 8 10 15 20 25 32 40 50 65 80 100

Quality Control All our factories maintain stringent quality control standards and inspection at all stages of manufacture which ensure that our products are fully suitable for general industrial use and will provide a long and reliable service. Every Econosto Valve is individually tested in accordance with the relevant product standard. Econosto valves are hydro-tested for 1.1 times the rated pressure for the seat closure test and 1.5 times the rated pressure for the shell test. After testing all valves are drained of water or test fluid. Iron Valves are coated with suitable coating to prevent it from rusting (either enamel paint, epoxy paint or suitable anti rust coating).

Testing Every ECONOSTO valve is individually tested in accordance with the relevant product standard. Test pressures and testing media are given on individual pages.

Seat Tightness Many valve product specifications, including British Standards require that there shall be no visible leakage through the valve seat under specified test conditions, but it is known in practice that normal test, whether hydrostatic or pneumatic, will for this one pressure excursion confirm the pressure integrity of the valve seat is satisfactory.

Subsequent tests on the same valve, even in the new condition will normally show the same result, but because later tests may be carried out in different conditions using different test equipment, test duration times, test pressures, test fluids, seating loads, etc., a different seat tightness condition may be found. American valve product standards including API, ANSI, MSS and ISO draft standards have acknowledged the impracticality of zero seat leakage concepts for certain industrial valves and maximum leakage rates are specified.

Leakage specifications to be meaningful and allow comparison should include test fluid, temperature, pressure, pressure drop, seating force and duration of test. Check valves which rely entirely on line pressure to effect closure cannot be guaranteed to provide tight shut off, especially on low pressures and/or gas services. Check valves having resilient disc facing will give tighter seating that metal to metal seated valves.

Specified permissible leakage should be based on process considerations (hazards resulting

from leakage after emergency shut off, etc.). Econosto (special) wedge gate valves with PTFE seat inserts are classified as tight shut off. Every Econosto valve will be tight under our normal works test conditions and as defined in the relevant product standards.

Inspection and Test Certificates Valve Test Certificates to DIN 50049 / EN 1024 can be provided against specific orders where requested and agreed

during enquiry and order stage. Where applicable additional fee will be charged. Third party inspections can also be arranged at additional costs.

Back Seating of Valves for re-packing The feasibility of re-packing high pressure-temperature valve stem stuffing boxes while the valve is wide open and under pressure has been discussed by the industry for several years now. One should understand here that the primary purpose of a valve is to stop, permit, or control the flow of fluids in a pipeline. All the valve manufacturers therefore lay special emphasis on providing the best combination of materials and design for the actual valve seating area . Therefore back seating to shut off pressure from the stuffing box is of relatively secondary importance.

Even though manufacturers pay special attention to seating surfaces and even though valves are carefully tested before they leave the manufacturer’s plant to make sure they are tight at seat, no manufacturer would unconditionally guarantee that the seat of the

In valve operation, normal wear and tear of the seating surfaces plus the possibility of corrosion, erosion, galling and the cutting / scratching effects of foreign matter could eventually lead to leakage through the valve seats. Of course leakage past the seat and disc is not acceptable to end users.

The back seat of the valve may not have the same quality / grade of materials that are used on the seats. The back seat surfaces, however, are subject to the same damaging effects that can produce leakage at the seat and disc. The back seat area might corrode, it might become covered with scale and foreign matter, or it might be galled or scored if excess force is applied while opening or closing the valve. Therefore if the user tries to re-pack under pressure a valve with damaged or corroded back seat there is a danger of accident or injury to the operator. The seriousness of the problem depends on the nature of installation.

Gate Valves

General Design & Application Econosto Gate Valves are highly reliable and dependable in service wherever minimum pressure drop is important. They serve as efficient stop / shut off valves with fluid flow in either direction. Because of its low resistance to flow when fully open the gate valve is particularly recommended for use in applications where minimum pressure drop is required. Gate valves are also known as isolating valves.

Where throttling is required, Econosto recommends the use of a globe valve. Close regulation is impossible with a regular Gate valve. Velocity of flow against a partly opened disc may cause vibration and chattering and result in damage to the seat surfaces and the internal assembly as well. Moreover when throttled the disc is subjected to severe wire-drawing erosive effects.

open or fully closed position and are not recommended for throttling. The straight

full bore design offers negligible resistance to flow and reduces the pressure drop to the minimum. All Econosto Gate Valves are designed with the wedge positively guided in the body by a slot on one part and a rib on the mating part. The positive guiding action allows the valve to be installed in any position on the line but whenever possible any valve should be installed in the vertical upright position. Econosto Valves are so designed that the wedge completely clears the waterway when fully open.

The Gate Valve bodies are designed in such a way that the entire valve has more rigidity under line strains, providing maximum strength and increased resistance to shock and distortion. Gate Valves are not recommended for use on lines containing abrasive materials due to the sliding action of the wedge against the body seat as the valve is open and closed. Also, Gate Valves should be opened and closed slowly to prevent setting up shock loads which could damage the valve and piping system. An added advantage to closing a gate valve slowly is the washing action which occurs due to the high velocity flow prior to closure. Econosto Gate Valves are available in non-rising stem (NRS) and rising stem (RS) for visual awareness and outside screw and yoke for isolation of stem threads from the line of flow. Rising stem valves with outside screw and yoke iron body gate valves are used on lines where corrosives, high temperatures and solids in the line may be damaging to stem threads. The outside thread design allows easy lubrication of the stem and indicates the position of the wedge (open or close). Non rising stem inside screw gate valves are used on lines where headroom is limited for operation and the stem does not rise vertically which helps to reduce the gland packing wear. The non-rising stem inside screw pattern has the stem actuating thread within the bonnet .

Gate Valves are designed for use in fully

Globe Valves

General Design & Application:

Econosto Globe Valves are very efficient for throttling service because disc and seat design provide the flow characteristics with proportional relationship between valve travel and flow rate. This assures accurate regulated flow.

Globe Valves with metal disc 45 degree should not be used for close throttling in high velocity

flow when erosion or wire drawing may result. For close throttling a plug type disc is recommended. Econosto Globe Valves are full port. This full port feature reduces the pressure drop to the minimum and also assures the end user of the full valve. As explained above Globe valves are generally recommended for use in services handling liquid, vapor or gas in applications where it is necessary to throttle or regulate the flow by positioning

the disc in fully open, fully closed or intermediate position. In addition to throttling, globe valves are recommended in applications where rapid cycle of operation is anticipated.

Due to the design of the Globe Valve the path of the fluid changes direction several times causing a condition of turbulent flow which in turn will cause an increase in the pressure drop through the valve. Due to this we do not recommend the use of the Globe Valve where the pressure drop has to be kept to a minimum. In applications where absolute minimum pressure drop plus positive closure is essential in such cases we recommend that the next larger size globe valve be installed by use of necessary connections rather than attempt to use a gate valve. Econosto Cast Iron Globe Valves have outside screw and yoke (OS & Y) construction. This design isolates the stem threads from heat and corrosive conditions inside the valve. It also enables the stem threads to be cleaned and lubricated easily.

Check Valves

General Design & Application: Econosto Check Valves allow flow in one direction only and close automatically when the flow reverses. These valves are entirely automatic in action. Check Valves depend upon the pressure and velocity of flow within the line to perform their functions of opening and closing.

As mentioned above the Check Valves are used to prevent the reversal of flow in piping systems. The valve is kept open by line pressure while closure is automatically activated by the reversal of flow by the weight of the disc mechanism. The disc and any other associated moving parts are always in a state of movement if the velocity of flow and pressure is not sufficient to hold the disc in wide open and stable / fixed position. This may lead to a high frequency noise also in the pipeline.

Premature wear and noisy operation or vibration can be avoided by selecting the size of the Check Valve on the basis of

flow conditions. The correct sizing of Check Valve is very important, particularly when the service is on water lines and other non-compressible materials. Proper sizing of Check Valves is very important for a maximum service life and so also is locating it away from the pulsating pump.

When used in proximity of a pump, we recommend that the Check Valve should be the same size as the discharge orifice on the pump. The reason being that the excessive turbulence through the Check Valve not only causes a clatter, but also results in rapid wear of the internal parts. Econosto Check Valves are available in various designs, materials and options. The Swing Check Valve with bronze seating is most commonly used. Due to its relative softness and ductility of the bronze seats it offers more positive sealing effect than would a harder material. Moreover the bronze seating is versatile in its suitability both as to temperature and various commonly handled materials. Wherever the service conditions permits we also recommend the use of check valves with rubber faced discs. The soft rubber offers substantial protection to the seat in cases where foreign materials are encountered in the line. The rubber faced disc also helps in services where due to the high head pressure, the flow is sharply reversed as it muffles the sound of the valve closing in addition to protecting the seat. Swing Check Valves with lever and weight can be used where there is a problem of pulsation in the lines and also for non-slam design. In this catalogue you will find mainly two types of Check Valves i.e. Swing Pattern and Wafer twin disc type.

Double Regulating Valves ( DRV)

General Design & Application: The Double Regulating Valves are also called Balancing Valves. Econosto Double Regulating and Commissioning Valves are installed in the pipe work of chilled water air conditioning and hot water central heating systems as well as potable water systems and serve to achieve a hydronic balance between the various circuits of the system. The balance

is achieved by a pre-setting with memory position. The required values of pre-setting can be obtained from the flow charts. All intermediate values are infinitely adjustable. The selected pre-setting can be read-off two scales (basic scale and fine adjustment scale). The Econosto double regulating and commissioning valves have two threaded ports for fill and drain ball valves or pressure test points for the measurement of differential pressure. The Econosto double regulating and

commissioning valves are delivered with 2 blind plugs as a standard unless test points are requested. The Econosto double regulating and commissioning valves may be installed in either the supply or the return pipe. The flow charts are valid for both cases provided the direction of flow conforms with the arrow marked on the valve body.

Advantages of Econosto DRV’s: - One valve for 3 functions:

Pre-setting, measuring and isolating - Low pressure loss

Unique design and oblique pattern - Infinitely adjustable pre-setting

Exact measurement of pressure loss by means of the pressure test points.

- Patented measuring channel

designed around the stem assembly to the test points ensures the best possible accuracy between differential pressure measured at the pressure test points and the actual differential pressure of the valve.

Distribution of flow : The main reason for these problems is that incorrect flows are available in the various circuits. If this is the case, the problem may be solved by installing a double regulating and commissioning valves or flow regulators in the corresponding pipes. The course of pressure in a circuit makes clear why this occurs.

total to guarantee a sufficient supply to appliance 4.This will however, inevitably result in a excessive differential pressure at the appliances 1 to 3 leading to an increased flow at these appliances and thus to an increased energy consumption. To remedy this, double regulating and commissioning are installed. The excess in differential pressure is now absorbed by the double regulating and commissioning valves. The desired flow rate may be controlled and set. To be able to control appliance 4 as well it is recommended to install a double regulating and commissioning valve here too. The correct supply of each appliance is now guaranteed.

The illustration shows that the pump has to produce a differential pressure of at least delta P -


Why do we need to Balance Air Conditioning Systems ? Balancing of heating and chilled water air conditioning systems is necessary to avoid the following problems : 1. Some rooms almost never achieve the desired room temperature or are not cooled sufficiently.

This problem especially arises in case of influence of other heat sources.

2. After changing over from low temperature to heating operation, parts of the system are only heated after a long time.

3. Fluctuating room temperatures especially arising during low demand periods. 4. High energy consumption although the required room temperature regulator is installed. Even high quality regulators may not solve this problem.

Wrong flow rates in the various circuits lead to an increased energy consumption. On the one hand, a higher pump capacity must be provided to guarantee a sufficient supply of each appliance and on the other hand appliances being installed at a favourable hydronic position are then over supplied. This will result in an increased room temperature or, in chilled water air conditioning systems, in too low a room temperature.If the average temperature in a building exceeds the nominal value by 1 degree C, the energy consumption is increased by 6 - 10 % . In chilled water air conditioning systems , temperatures being 1 degree C too low will result in an increase in energy consumption of about 15%. Note: Periodical maintenance is required (at least once in 6 months) for large diameter Balancing Valves (DRV’s of 200mm & above). It is suggested to open and close the balancing valves (DRV) a few times once in every 6 months to ensure that no contaminants are trapped with in the trim of the valve. It is also recommended to install another isolating valve (Wafer butterfly valves are recommended) on the discharge side of large size Balancing Valves (DRV) for any required maintenance or replacement of equipment or balancing valves.

General Design & Application

Econ Automatic flow control valves (flow limiter) are designed to maintain (limit) a preset specified flow rate with in a specified pressure differential ( p) range. The flow shall be varying above and below the specified p range across the AFCV.

The AFCV is equipped with a flow rate cartridge which has a SS 316 cylinder where orifice areas (through which the liquid flows) are cut and is fixed to a POM body along with the SS spring. The basic flow equation can be simplified as: Q = A x p, where Q = Flow rate A = Area

p = Differential pressure

The cartridge is designed to change the orifice area in order to maintain the constant flow when changes in p occurs across it due to various reasons (with in the specified p range). Below and above the p range, the cartridge acts as a fixed orifice and the flow will vary as per the differential pressure available. According to the below figure, we can see that the flow is maintained with in the p range. These valves will automatically balance the entire circuit, irrespective of constant flow or a variable flow system.

Selection

Q

p range determines the range of minimum and maximum differential pressure the valve will

experience during the course of operation in the sub circuit where it is installed. Select the cartridge p range from the flow chart given, which will accommodate both these minimum and maximum values. Flow rate : The flow rate is selected close to the design flow rate from the various flow rates shown in the above selected p range from the flow chart.

Advantages of AFCVs over DRVs

Manual Balancing

Automatic Balancing

DRV's are required on the main headers, risers , branches and the individual terminal units.

AFCV's are required only on the terminal units (FCU's, AHU's, Heat exchangers etc.)

As there are more balancing valves required on manual balancing systems, the total head loss or the pressure drop of the index circuit will be higher and thus higher pump head and higher pumping costs.

The elimination of partner balancing valves on the headers, risers and the branches in turn, eliminates the pressure drop through them. Hence the system loss is reduced and thus less pump head which lowers the pumping costs.

In constant speed systems, one additional balancing valve is required on the bypass of the 3 way control valve of terminal units, to balance the bypass.

In constant speed systems, only one AFCV is required which will control the total flow of the coil.

The performance of a DRV is affected if its installation is not done in accordance with the specified straight length requirements.

No straight length requirement for installing AFCV's. Proximity to pipe bends, fittings etc., upstream or down stream location, horizontal or vertical orientation, does not affect its performance.

The commissioning of DRV systems cause time and money.

There is no commissioning required for AFCV systems. Only minimal labour required for flow verification.

Even after the tedious commissioning procedures, the flow accuracy achieved will only be in the range of 20-25%

The flow accuracy of AFCV's : 5-8%

Any pressure fluctuation in the system will alter the differential pressure ( P)across the DRV and thus the altering flow , as the Kv value( Orifice area) is fixed while commissioning.

A change in differential pressure across the AFCV does not change flow through it, if the P is with in the specified range.

The under flow and overflow situations will occur in the terminals under partial load conditions in the variable speed pumping systems. The overflows shall be as big as 200 - 300% of designed flows.

AFCV systems does not experience any over flow or underflow situation if the Ps are maintained with in the specified limits and they are 100% safe from overflow and underflow situations.

Stage by stage commissioning of projects with large number of terminal units will cause imbalance of the previously commissioned phases and rebalancing of the system is required on each stage.

Building renovation requires rebalancing of the whole system.

Stage by stage commissioning does not affect the previously started stages as the

P variations will be taken care by each AFCVs.

AFCV system does not require any adjustments due to the renovations.

Any pressure fluctuation in the system will alter the differential pressure ( P)across the DRV and thus the altering flow , as the Kv value( Orifice area) is fixed while commissioning.

A change in differential pressure across the AFCV does not change flow through it, if the P is with in the specified range.

The under flow and overflow situations will occur in the terminals under partial load conditions in the variable speed pumping systems. The overflows shall be as big as 200 - 300% of designed flows.

AFCV systems does not experience any over flow or underflow situation if the Ps are maintained with in the specified limits and they are 100% safe from overflow and underflow situations.

Stage by stage commissioning of projects with large number of terminal units will cause imbalance of the previously commissioned phases and rebalancing of the system is required on each stage.

Building renovation requires rebalancing of the whole system.

Stage by stage commissioning does not affect the previously started stages as the

P variations will be taken care by each AFCVs.

AFCV system does not require any adjustments due to the renovations.

Strainers


Solid contamination is detrimental to the performance and life of fluid transfer systems. It is therefore extremely important to remove solid contamination from fluid transfer systems. This will protect the pipeline and all the associated equipment / instruments on the line which are many a times sensitive to dirt.

Corrosion deposits, scaling, welding slag, sealing compounds as well as several other materials are trapped and prevented from causing system contamination and subsequent problems and failures. The ECON ‘Y’ type strainer design offers a reliable and cost effective means of equipment protection, minimizing downtime and maintenance costs.

The design of ECON strainers is supported by the decades of experience in the field of fluid handling.

Straining is a process of directly intercepting solid particles when the fluid passes through the strainer element / perforated screen. The strainer screen perforations / mesh size are small enough to prevent passage of solid contamination / dirt to the downstream. The ECON bronze strainers have a strong stainless steel wire mesh screen / element insert. The holes on the wire mesh are of size 0.8 mm. The larger size ‘ECON’ Cast Iron strainers have a solid stainless steel perforated screen / element with a hole size of 1.5 mm. The pressure drop through the ECON strainers is minimized due to its streamlined flow design. The strainers have a compact design. Also suitable for saturated steam service. ECON strainers can be supplied with a drain plug fixed on the strainer bottom cover as an additional / optional feature where requested. Note: It is extremely important that the Strainer screen is cleaned at frequent intervals in order to avoid damage to screens / elements due to choking (dirt build-up). This will also help to get a better life from the Strainer screen / element. We strongly advice that the Strainer screen are cleaned at regular intervals especially during initial flushing and start up.

Expansion Joints


Econosto’s ECONFLEX expansion joints are installed to accommodate movement in piping runs, protect piping from expansion and contraction and ensure efficient and economical on-stream operations. Rubber expansion joints provide time tested ways to accommodate pressure loads, relieve movements stresses, reduce noise, isolate vibrations, compensate for mis-alignment after plans go on stream and prolong the life of motive equipment. Rubber expansion joints are used in all systems conveying fluids under pressure and / or vacuum at various temperatures.

1. Absorbs Vibration, Noise and Shock Sound, travelling axially through ECONFLEX expansion joints, is stopped at once. Water hammer, pumping impulses and water borne noises are absorbed by the moulded light-weight thin-wall structure. 2. Easy to Install and Remove Floating flanges, no need of gasket or packing, and elastic spherical body make the joint easy to install or remove. 3. Security Assured in Usage Special spherical carcass enables its body, when subjected to high pressure and expansion, not contacting with the connecting bolt head.

Thus, the joint may be used in a sense of damage proof and full security. 4. Higher Burst Strength Spherical shape is stronger than cylindrical shape or other configuration. Thus under pressure, ECONFLEX expansion joint is 4 times as strong as a cylindrical joint, Additionally, our products are made of best suitable material, and hence their burst pressure is much higher than others. 5. Suitable for Suction and Delivery (Discharge) Owing to its excellent molding technique with its tough chemical fiber, ECONFLEX expansion joints can satisfactorily withstand the suction and discharge. Vacuum rating can stand up to 750 mm Hg. 6. High Efficiency ECONFLEX expansion joint has streamlined, flowing arch to reduce turbulence, sediment build-up, thrust area and the effects of thrust on the piping system equipment. 7. Low Deformation under Pressure Internal pressure is exerted in all directions distributing forces evenly over a large area. Hence, the deformation of ECONFLEX expansion joint due to pressure is much lower than that of other makers. 8. Light and Compact The space required for the installation of ECONFLEX expansion joints is about half of the requirement of cylindrical. Weight is about one third. 9. Greater Movements are available Axial compression and elongation, deflection and angular movements will be greater. 10. Wide Service Range Made with chemical resistant elastomers such as Neoprene, Nitrile, Hypalon. EPDM: ensures a product compatible with the fluid being pumped or piped. Operate up to 16KG and - 20°C to 100°C

Mounting Instructions 1. The alignment of the piping system should be adjusted and secured with fixation points as close as possible on each side of the expansion joints at a distance less than 3 times the pipes nominal diameter. 2. These fixation points must be installed when mounting an expansion joint with control rods or in a case of an elbow pipe. If there is a considerable distance between 2 fixation points, guiding points can be installed in order to support and guide the pipe. 3. (A) When installing take care the rubber expansion joint don’t support compression or extension due to the weight of the upstream or downstream pipe.

Mounting order: a - Upstream pipe: anchor b - Downstream pipe: anchor c - Expansion joint

(B) When installing the rubber expansion joint take care that it must not be twisted in any case. 4. Verify that the upstream and downstream pipe alignment does not deviate more than 1/8” (3mm) and that the expansion joint does not support heavy weight. 5. Verify that the surfaces coming in contact with the joint are perfectly clean and without cutting edges (pipe) thus avoiding damage to the joint surface. 6. Insert the bolts on the arch side of the joint, thus avoiding direct contact with the rubber. 7. If welding is carried out within close range, cover or dismount the expansion joint. 8. Do not paint or coat the joint with insulation. 9. During installation, the pre-compression should not exceed 5mm. 10.Store the joint the flat position avoiding humidity and extreme temperatures. Note: Bolt tightness should be checked daily within the first month (one week) after services and checked periodically thereafter.

Anchoring and Guiding the Piping System

Rubber expansion joint should be located close to a main anchoring point. Following the rubberexpansion joint in the line, a pipe guide or guides should be installed to keep the pipe in line and prevent undue displacement of this line.

Anchors are Required

Branch Connection Anchor

Figure B is another illustration of the proper anchoring that should be provided in a line with a branch connection. The anchor shown at the tee and elbow connections must be designed to withstand both the thrust and any other forces imposed on the system at these points. Again emphasis is placed on the relative location of joints, their anchoring points and the pipe guides.

Figure A illustrates a simple piping system. You will notice in all cases simple anchoring is provided wherever the pipeline changes direction and that the expansion joints in that line are located as close as possible to those anchor points. In addition, following the expansion joints, and again as close is practical, pipe guides are employed to prevent displacement of the pipeline. It should be pointed out that the elbows adjacent to the pump are securely supported by the pump base so that no piping forces are transmitted to the Anchors shown at the 90 Degree and the 45 Degree bend in the pipeline must be solid anchors designed to withstand the thrust developed in the line together with any other forces imposed on the system at this point.
