Diaphragm valves are popular in a wide variety of industries, including agriculture, biopharmaceuticals, chemical processing, energy production, food processing, irrigation, medicine, mining, plumbing, pulp and paper, and water treatment.

The earliest diaphragm valves were made by the Greeks and Romans. They used them to regulate the flow and temperature of water used in hot baths. Early Greek and Roman diaphragm valves consisted of a leather diaphragm that sealed when an operator manually pressed the diaphragm into a raised section called a weir.

The diaphragm valves of these ancient societies were largely forgotten until the turn of the 20th century, when a South African mining engineer, P.K. Saunders, read about them while studying ancient history for fun. At the same time, he was attempting to design an improved underground mining valve system. This was because the ones people worked with bled money from leaky valves and frequently lost power. Inspired by the Greeks and Romans, Saunders fixed this problem by designing his own diaphragm valve. Recognizing that he had come up with something great, Saunders took it upon himself to take out several patents on his valve. Eventually, he licensed a number of different companies, allowing them to produce the diaphragm valve. The first American company to produce the diaphragm valve was the Hills McCanna Company, which started distributing them in 1931.

The next step in the journey of diaphragm valves was their union with new materials, like advanced elastomers and improved plastics. For a long time, diaphragm valves were operated manually, but eventually manufacturers largely switched over to automated valves. To make this happen, manufacturers began manufacturing diaphragm valves with actuators. Actuators made diaphragm valves more reliable and efficient.

Today diaphragm valve manufacturers make their products using a wide range of configurations and materials. Diaphragm valves are more well-made, trustworthy, and diverse than ever. For example, engineers have developed diaphragm valves so much that many are suitable for use in the bio-pharmaceutical industry. Only time will tell where engineers will take them next.

The materials with which manufacturers make a diaphragm valve must be chemically compatible with the material flowing through the valve. They must also be durable. If the materials are not, the valve will likely sustain damage that can lead to product contamination. Materials and compositions they may encounter include adhesives, chemicals, cleaners, coatings, colorants, fuel, paints, silicones, and water.

Manufacturers most often make diaphragm valve bodies from materials such as brass, cast iron, CPVC, PVC, stainless steel, and steel. They favor materials like stainless steel for the valve body because such materials are corrosion resistant, durable, and strong.

The actual diaphragm is made of various elastomers, like polyethylene and polypropylene, and others like those used to line the valve mechanism. If the diaphragm will encounter highly abrasive materials, manufacturers can reinforce it with mesh fibers.

When designing a diaphragm valve, manufacturers consider factors such as projected space and application diameter and dimensions, frequency of operation, media type, temperature and pressure ratings, process stream velocity, and required end connections. Based on these considerations, they can select the right type of valve, valve material, diaphragm material, valve shape and size, and valve controls. Manufacturers can customize any and all of these valve details to fit your application.

Valves may be manual, automatic, pneumatic, electric, or hydraulic. Typically, they feature a body, piping, an actuating device (actuator), a stem, and a diaphragm. The body is spherical or cylindrical and contains both the actuating device and stem. The stem is a rod or piston.

The diaphragm sits in front of the stem. The piping, which is connected to the valve body, features a raised bump. Hydraulic fluid, compressed air, or manual turning action causes the stem to press down against the diaphragm. This causes the diaphragm to expand to a new depth, blocking the piping and the fluids that pass through it. This is the closed position. In the open position, the stem retracts, so that the diaphragm goes back to its original position and fluid can pass by.

Something to note about the actuator is the fact that it boosts the capabilities of clean valve operation because of the broad possibilities they offer. Clean valve operations are important to many of the applications for which diaphragm valves are used, and so many of them require enhanced valves, such as hygienic valves, biotech valves, or sanitary diaphragm valves.

Diaphragm control valves allow manufacturers to modify pressure, temperature flow rates, and liquid levels as they go along. They do so with the assistance of a diaphragm made of an elastomer film or membrane.

In turn, check valves and control valves are further divided into two configuration groups: seat valves and saddle valves, or straight-way and weir valves, respectively.

Both of these valve types feature two or more ports through which materials flow. With both, one port serves as an inlet and at least one other serves as a place for exhaust to escape from the body. When the valve is not engaged, materials will simply flow in one port and out the other, but when it is, flow becomes restricted or completely repressed.

Seat valve bodies use a 90° bend to cause the directional change of a process stream as it moves around a corner. Essentially, seat valves create a nonlinear stream path. Most often, seat valves are used to facilitate angled flow in cistern or tank bottoms.

Saddle valves, on the other hand, direct flow with two ports that are located opposite one another. Essentially, saddle valves create and regulate a linear stream path. Typically, they assist pre-existing flow lines.

Aside from the difference in piping or tubing angle, seat valves and saddle valves are essentially the same. To begin with, they both consist of a spherical or cylindrical body, attached to the tubing or tank that requires the valve, which contains the actuation device and diaphragm. They both also have the same type of diaphragm. The diaphragm of both is thin at the edges and thick in the middle, a feature that permits easy stretching. It lifts up when the valve is opened, allowing for gases or fluids to pass. When the valve is closed, the stem engages the diaphragm by applying pressure. This pressure forces the diaphragm to move towards the opposite wall of the piping to create a flexible but effective flow barrier.

Other diaphragm valve types include process valves, zero static valves, sanitary diaphragm valves, diaphragm solenoid valves, direct acting diaphragm solenoid valves, indirect acting diaphragm solenoid valves, shut-off valves, pneumatic diaphragm valves, and diaphragm actuated gate valves.

Zero static valves are another diaphragm valve type that are great for clean operations, because they eliminate the opportunities for bacterial growth and flow stagnation.

Diaphragm solenoid valves are a variation on the regular solenoid valve, which is an electromechanical valve used for flow control. Along with a solenoid coil, diaphragm solenoid valves usually feature rubber diaphragms situated inside of the valve body. They open and close against a hard seat. They may be direct acting or indirect acting.

Direct acting diaphragm solenoid valves change their diaphragm position only when the solenoid coil energizes. When this happens, the diaphragm opens or closes, depending if the valve is normally open or normally closed.

Indirect acting diaphragm solenoid valves, also known as pilot operated diaphragm solenoid valves, require diaphragm pressure to work. They change their diaphragm position when the fluid flowing through a valve gathers enough pressure. In other words, the media pressure acts as a pilot, directing the diaphragm position.

Pneumatic diaphragm valves are automated diaphragm valves that use pneumatic controls with an elastomeric membrane. They are popular because they only require the compressed air to expand and contract the diaphragm materials.

Diaphragm actuated gate valves are bi-directional flow safety valves. They combine the strategies used by diaphragm and gate valves to create an extremely reliable hybrid. They feature two floating seats, a slab gate, and a spring return diaphragm actuator.

Diaphragm valves offer their users a wide variety of advantages. First, they are easy to install. Second, they are reliable and easy to maintain. Another benefit of diaphragm valves is the fact that they can resist corrosion and other damage from both harsh chemicals and radioactive fluids. Also, unlike some other valves, slurries, solids and the like will not get caught in air pockets. So, they are more efficient than others and they are less likely to catch and transport impurities.

Manufacturers may recommend any number of accessories for use with your diaphragm valve, depending on your application. Examples of some common diaphragm valve accessories include o-ring sealed bonnets, direct loaded bonnets, extended stems, gear boxes, positioners, solenoids, mounting brackets, and more.

To maintain the health of their diaphragm valve, customers must conduct routine cleaning and maintenance. Doing so ensures efficiency and a lack of leakage.

If you are in the market for diaphragm valves, you get the results you want by pairing with a high-quality valve manufacturer or supplier. To assist you in locating such an entity, we have put together a comprehensive list of those diaphragm valve manufacturers we trust most. You will find company information, complete with profiles, wedged in between the industry info.

Before you start looking at manufacturers, though, we recommend you take some time to jot down your specifications. Make sure to include not only your technical specifications, but also things like your budget, your timeline, your delivery preferences, and your post-delivery support preferences (installation assistance, parts replacement, etc.). Once you have done that, you are ready to start looking for your manufacturer. As you browse, keep your specifications at the forefront of your mind. Select three or four diaphragm valve manufacturing companies in which you are most interested, and then reach out to each of them. Discuss your application at length; don’t be afraid to ask a lot of questions. One of the many signs of a good company is a helpful and engaging sales staff. If they are impatient with your questions, you might not want to work with them. Once you have spoken with each manufacturer, compare and contrast their services and offerings, and pick the right one for you.

The Simtech SBR Series Diaphragm Pressure Relief Valve is designed to protect piping and equipment from pressure changes where a rapid release of excess pressure is required. Prevents pumps from dead heading, over pressurization, pressure surge conditions, and maintains back pressure in closed loop systems. Adjustable screw and lock-nut makes it easy to accurately preset desired relief pressure.

Emergency situations are not the only times relief valves are active; once installed they continuously regulate the flow of substance. They can also be pre-set to open when the pressure or temperature gets to a certain point that may be dangerous. Generally valves are placed on or near the pump head of the hose, pipe or tube. A wide variety of relief valve designs exist, although most resemble ball-check valves, swing check valves or diaphragm valves.

This last is particularly useful when controlling a flow of fluids that contains suspended solids. Most relief valves are spring operated, as are the majority of check valves. One specialized type of relief valve is known as a vacuum relief valve. As opposed to a normal relief valve, which relieves high pressure, a vacuum relief valve is used to relieve dangerously low pressures, or vacuums, by inserting air or an inert gas.

Like every other type of check valve, relief valves may be constructed from a variety of materials, including PVC, brass, ductile iron, copper, polyethylene, polypropylene, aluminum, steel, stainless steel and rubber. Which raw substance is used to produce each relief valve depends on the environment said relief valve will be in. The wrong product could result in erosion or contamination of the process stream. However, as long as research is done, finding the appropriate type of relief valve is possible. Every plumbing or fluid transfer application in the industrial, commercial and domestic arenas employ or will employ check valves. In fact, check valves of all kinds are an essential part of every day life. Because they need not be supervised to function and prevent product malfunction, check valves are not only desirable but often required by law to ensure the safety of water, gas and pressure applications.

It uses a diaphragm structure with only highly inert wetted materials such as PTFE, PPS, and FFKM and can handle severe media with strong acids and strong alkalis.

The valve opens, and the media flows to the secondary port when the primary pressure exceeds the relief pressure, preventing the flow channel from rising further.

There is a wide range of safety valves available to meet the many different applications and performance criteria demanded by different industries. Furthermore, national standards define many varying types of safety valve.

The ASME standard I and ASME standard VIII for boiler and pressure vessel applications and the ASME/ANSI PTC 25.3 standard for safety valves and relief valves provide the following definition. These standards set performance characteristics as well as defining the different types of safety valves that are used:

ASME I valve - A safety relief valve conforming to the requirements of Section I of the ASME pressure vessel code for boiler applications which will open within 3% overpressure and close within 4%. It will usually feature two blowdown rings, and is identified by a National Board ‘V’ stamp.

ASME VIII valve- A safety relief valve conforming to the requirements of Section VIII of the ASME pressure vessel code for pressure vessel applications which will open within 10% overpressure and close within 7%. Identified by a National Board ‘UV’ stamp.

Full bore safety valve - A safety valve having no protrusions in the bore, and wherein the valve lifts to an extent sufficient for the minimum area at any section, at or below the seat, to become the controlling orifice.

Conventional safety relief valve -The spring housing is vented to the discharge side, hence operational characteristics are directly affected by changes in the backpressure to the valve.

Balanced safety relief valve -A balanced valve incorporates a means of minimising the effect of backpressure on the operational characteristics of the valve.

Pilot operated pressure relief valve -The major relieving device is combined with, and is controlled by, a self-actuated auxiliary pressure relief device.

Power-actuated safety relief valve - A pressure relief valve in which the major pressure relieving device is combined with, and controlled by, a device requiring an external source of energy.

Standard safety valve - A valve which, following opening, reaches the degree of lift necessary for the mass flowrate to be discharged within a pressure rise of not more than 10%. (The valve is characterised by a pop type action and is sometimes known as high lift).

Full lift (Vollhub) safety valve -A safety valve which, after commencement of lift, opens rapidly within a 5% pressure rise up to the full lift as limited by the design. The amount of lift up to the rapid opening (proportional range) shall not be more than 20%.

Direct loaded safety valve -A safety valve in which the opening force underneath the valve disc is opposed by a closing force such as a spring or a weight.

Proportional safety valve - A safety valve which opens more or less steadily in relation to the increase in pressure. Sudden opening within a 10% lift range will not occur without pressure increase. Following opening within a pressure of not more than 10%, these safety valves achieve the lift necessary for the mass flow to be discharged.

Diaphragm safety valve -A direct loaded safety valve wherein linear moving and rotating elements and springs are protected against the effects of the fluid by a diaphragm

Bellows safety valve - A direct loaded safety valve wherein sliding and (partially or fully) rotating elements and springs are protected against the effects of the fluids by a bellows. The bellows may be of such a design that it compensates for influences of backpressure.

Controlled safety valve - Consists of a main valve and a control device. It also includes direct acting safety valves with supplementary loading in which, until the set pressure is reached, an additional force increases the closing force.

Safety valve - A safety valve which automatically, without the assistance of any energy other than that of the fluid concerned, discharges a quantity of the fluid so as to prevent a predetermined safe pressure being exceeded, and which is designed to re-close and prevent further flow of fluid after normal pressure conditions of service have been restored. Note; the valve can be characterised either by pop action (rapid opening) or by opening in proportion (not necessarily linear) to the increase in pressure over the set pressure.

Direct loaded safety valve -A safety valve in which the loading due to the fluid pressure underneath the valve disc is opposed only by a direct mechanical loading device such as a weight, lever and weight, or a spring.

Assisted safety valve -A safety valve which by means of a powered assistance mechanism, may additionally be lifted at a pressure lower than the set pressure and will, even in the event of a failure of the assistance mechanism, comply with all the requirements for safety valves given in the standard.

Supplementary loaded safety valve - A safety valve that has, until the pressure at the inlet to the safety valve reaches the set pressure, an additional force, which increases the sealing force.

Note; this additional force (supplementary load), which may be provided by means of an extraneous power source, is reliably released when the pressure at the inlet of the safety valve reaches the set pressure. The amount of supplementary loading is so arranged that if such supplementary loading is not released, the safety valve will attain its certified discharge capacity at a pressure not greater than 1.1 times the maximum allowable pressure of the equipment to be protected.

Pilot operated safety valve -A safety valve, the operation of which is initiated and controlled by the fluid discharged from a pilot valve, which is itself, a direct loaded safety valve subject to the requirement of the standard.

The common characteristic shared between the definitions of conventional safety valves in the different standards, is that their operational characteristics are affected by any backpressure in the discharge system. It is important to note that the total backpressure is generated from two components; superimposed backpressure and the built-up backpressure:

Subsequently, in a conventional safety valve, only the superimposed backpressure will affect the opening characteristic and set value, but the combined backpressure will alter the blowdown characteristic and re-seat value.

The ASME/ANSI standard makes the further classification that conventional valves have a spring housing that is vented to the discharge side of the valve. If the spring housing is vented to the atmosphere, any superimposed backpressure will still affect the operational characteristics. Thiscan be seen from Figure 9.2.1, which shows schematic diagrams of valves whose spring housings are vented to the discharge side of the valve and to the atmosphere.

By considering the forces acting on the disc (with area AD), it can be seen that the required opening force (equivalent to the product of inlet pressure (PV) and the nozzle area (AN)) is the sum of the spring force (FS) and the force due to the backpressure (PB) acting on the top and bottom of the disc. In the case of a spring housing vented to the discharge side of the valve (an ASME conventional safety relief valve, see Figure 9.2.1 (a)), the required opening force is:

In both cases, if a significant superimposed backpressure exists, its effects on the set pressure need to be considered when designing a safety valve system.

Once the valve starts to open, the effects of built-up backpressure also have to be taken into account. For a conventional safety valve with the spring housing vented to the discharge side of the valve, see Figure 9.2.1 (a), the effect of built-up backpressure can be determined by considering Equation 9.2.1 and by noting that once the valve starts to open, the inlet pressure is the sum of the set pressure, PS, and the overpressure, PO.

Once the valve starts to open, the effects of built-up backpressure also have to be taken into account. For a conventional safety valve with the spring housing vented to the discharge side of the valve, see Figure 9.2.1 (a), the effect of built-up backpressure can be determined by considering Equation 9.2.1 and by noting that once the valve starts to open, the inlet pressure is the sum of the set pressure, PS, and the overpressure, PO.

Balanced safety valves are those that incorporate a means of eliminating the effects of backpressure. There are two basic designs that can be used to achieve this:

Although there are several variations of the piston valve, they generally consist of a piston type disc whose movement is constrained by a vented guide. The area of the top face of the piston, AP, and the nozzle seat area, AN, are designed to be equal. This means that the effective area of both the top and bottom surfaces of the disc exposed to the backpressure are equal, and therefore any additional forces are balanced. In addition, the spring bonnet is vented such that the top face of the piston is subjected to atmospheric pressure, as shown in Figure 9.2.2.

The bellows arrangement prevents backpressure acting on the upper side of the disc within the area of the bellows. The disc area extending beyond the bellows and the opposing disc area are equal, and so the forces acting on the disc are balanced, and the backpressure has little effect on the valve opening pressure.

Bellows failure is an important concern when using a bellows balanced safety valve, as this may affect the set pressure and capacity of the valve. It is important, therefore, that there is some mechanism for detecting any uncharacteristic fluid flow through the bellows vents. In addition, some bellows balanced safety valves include an auxiliary piston that is used to overcome the effects of backpressure in the case of bellows failure. This type of safety valve is usually only used on critical applications in the oil and petrochemical industries.

Since balanced pressure relief valves are typically more expensive than their unbalanced counterparts, they are commonly only used where high pressure manifolds are unavoidable, or in critical applications where a very precise set pressure or blowdown is required.

This type of safety valve uses the flowing medium itself, through a pilot valve, to apply the closing force on the safety valve disc. The pilot valve is itself a small safety valve.

The diaphragm type is typically only available for low pressure applications and it produces a proportional type action, characteristic of relief valves used in liquid systems. They are therefore of little use in steam systems, consequently, they will not be considered in this text.

The piston type valve consists of a main valve, which uses a piston shaped closing device (or obturator), and an external pilot valve. Figure 9.2.4 shows a diagram of a typical piston type, pilot operated safety valve.

The piston and seating arrangement incorporated in the main valve is designed so that the bottom area of the piston, exposed to the inlet fluid, is less than the area of the top of the piston. As both ends of the piston are exposed to the fluid at the same pressure, this means that under normal system operating conditions, the closing force, resulting from the larger top area, is greater than the inlet force. The resultant downward force therefore holds the piston firmly on its seat.

If the inlet pressure were to rise, the net closing force on the piston also increases, ensuring that a tight shut-off is continually maintained. However, when the inlet pressure reaches the set pressure, the pilot valve will pop open to release the fluid pressure above the piston. With much less fluid pressure acting on the upper surface of the piston, the inlet pressure generates a net upwards force and the piston will leave its seat. This causes the main valve to pop open, allowing the process fluid to be discharged.

When the inlet pressure has been sufficiently reduced, the pilot valve will reclose, preventing the further release of fluid from the top of the piston, thereby re-establishing the net downward force, and causing the piston to reseat.

Pilot operated safety valves offer good overpressure and blowdown performance (a blowdown of 2% is attainable). For this reason, they are used where a narrow margin is required between the set pressure and the system operating pressure. Pilot operated valves are also available in much larger sizes, making them the preferred type of safety valve for larger capacities.

One of the main concerns with pilot operated safety valves is that the small bore, pilot connecting pipes are susceptible to blockage by foreign matter, or due to the collection of condensate in these pipes. This can lead to the failure of the valve, either in the open or closed position, depending on where the blockage occurs.

The terms full lift, high lift and low lift refer to the amount of travel the disc undergoes as it moves from its closed position to the position required to produce the certified discharge capacity, and how this affects the discharge capacity of the valve.

A full lift safety valve is one in which the disc lifts sufficiently, so that the curtain area no longer influences the discharge area. The discharge area, and therefore the capacity of the valve are subsequently determined by the bore area. This occurs when the disc lifts a distance of at least a quarter of the bore diameter. A full lift conventional safety valve is often the best choice for general steam applications.

The disc of a high lift safety valve lifts a distance of at least 1/12th of the bore diameter. This means that the curtain area, and ultimately the position of the disc, determines the discharge area. The discharge capacities of high lift valves tend to be significantly lower than those of full lift valves, and for a given discharge capacity, it is usually possible to select a full lift valve that has a nominal size several times smaller than a corresponding high lift valve, which usually incurs cost advantages.Furthermore, high lift valves tend to be used on compressible fluids where their action is more proportional.

In low lift valves, the disc only lifts a distance of 1/24th of the bore diameter. The discharge area is determined entirely by the position of the disc, and since the disc only lifts a small amount, the capacities tend to be much lower than those of full or high lift valves.

Except when safety valves are discharging, the only parts that are wetted by the process fluid are the inlet tract (nozzle) and the disc. Since safety valves operate infrequently under normal conditions, all other components can be manufactured from standard materials for most applications. There are however several exceptions, in which case, special materials have to be used, these include:

Cast steel -Commonly used on higher pressure valves (up to 40 bar g). Process type valves are usually made from a cast steel body with an austenitic full nozzle type construction.

For all safety valves, it is important that moving parts, particularly the spindle and guides are made from materials that will not easily degrade or corrode. As seats and discs are constantly in contact with the process fluid, they must be able to resist the effects of erosion and corrosion.

The spring is a critical element of the safety valve and must provide reliable performance within the required parameters. Standard safety valves will typically use carbon steel for moderate temperatures. Tungsten steel is used for higher temperature, non-corrosive applications, and stainless steel is used for corrosive or clean steam duty. For sour gas and high temperature applications, often special materials such as monel, hastelloy and ‘inconel’ are used.

Standard safety valves are generally fitted with an easing lever, which enables the valve to be lifted manually in order to ensure that it is operational at pressures in excess of 75% of set pressure. This is usually done as part of routine safety checks, or during maintenance to prevent seizing. The fitting of a lever is usually a requirement of national standards and insurance companies for steam and hot water applications. For example, the ASME Boiler and Pressure Vessel Code states that pressure relief valves must be fitted with a lever if they are to be used on air, water over 60°C, and steam.

A test gag (Figure 9.2.7) may be used to prevent the valve from opening at the set pressure during hydraulic testing when commissioning a system. Once tested, the gag screw is removed and replaced with a short blanking plug before the valve is placed in service.

The amount of fluid depends on the particular design of safety valve. If emission of this fluid into the atmosphere is acceptable, the spring housing may be vented to the atmosphere – an open bonnet. This is usually advantageous when the safety valve is used on high temperature fluids or for boiler applications as, otherwise, high temperatures can relax the spring, altering the set pressure of the valve. However, using an open bonnet exposes the valve spring and internals to environmental conditions, which can lead to damage and corrosion of the spring.

When the fluid must be completely contained by the safety valve (and the discharge system), it is necessary to use a closed bonnet, which is not vented to the atmosphere. This type of spring enclosure is almost universally used for small screwed valves and, it is becoming increasingly common on many valve ranges since, particularly on steam, discharge of the fluid could be hazardous to personnel.

Some safety valves, most commonly those used for water applications, incorporate a flexible diaphragm or bellows to isolate the safety valve spring and upper chamber from the process fluid, (see Figure 9.2.9).

An elastomer bellows or diaphragm is commonly used in hot water or heating applications, whereas a stainless steel one would be used on process applications employing hazardous fluids.
