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.

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.

Also known as pressure relief valves (PRV), pressure safety valves (PSV), and safety valves, these systems act as a safety measure. They relieve excess pressure from equipment failure, process upset, or fire by opening an auxiliary passage to divert the fluid (liquid, gas, steam or air) away from the pressure vessel. Once the pressure in the vessel is released and the danger is over the relief valve closes itself. 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.

Pressure relief valve is installed on the outlet pipe of water supply pipeline. It can maintain safe water supply pressure inside the pipe and prevent pipeline and equipment damage caused by accidental escalation of water pressure.

When water pump stops functioning or pipeline gate suddenly closes, abnormal pressure forms inside the pipe. As the pressure gets over a certain the water high pressure. When pressure returns to safety value, pressure relief valve will auto-matically close to ensure the safety of equipment.

Relief and safety Valves are used in high pressure systems to control the pressure and keep balance of the system. The different between safety valves and relief valves is that the safety valves fully open or close under a certain pressure while the relief valves can open in proportion to the pressure in front of them. The safety and pressure relief valves are used automatically. They both operate under similar conditions. When the pressure builds up in a system, it has to be managed by releasing the material to flow through. These valves have a threshold pressure at which they open. The consolidated safety and safety relief valves comprise of a bonnet vent and bellow with springs.

The springs are set up for the threshold pressure and when the pressure exceeds the threshold, the spring is pushed into the bonnet vent and the bellow opens the valve. The Safety Relief Valves can be open and shut valves. They either open or shut off at any given pressure. This is mostly for the safety of an application not to explode under high pressure. The Pressure Relief Valve on the other hand releases the material after the threshold pressure, but not fully. If the pressure is slightly higher the threshold, then the valve opens slightly. If the pressure is very high above the threshold, it opens wider. It also functions in the same manner when the pressure drops down. The valve closes in proportion to the pressure. The safety valve shuts down at once only when the pressure is below the threshold.

Relief Valves are designed to control pressure in a system While Safety Valves are used for controlling the pressure in a system they release pressure immediately in the event of an emergency or system failure

The Setpoint of relief valve is usually set at 10 Percent above working pressure limit while safety valve is usually set at 3% above working pressure limit.

If you are operating systems that can only be off for short periods of time, it is sensible to keep a spare valve to swap over and then the removed valve can be inspected and recertified.

The valve will relieve at a preset pressure, then reseat itself automatically when safe working pressure is restored. Adjustment from the original pressure setting is provided within the following limits; plus or minus 20 psig. if the original setting is 30 psig. or higher. If the original setting is 10 psig. the adjustment available is plus 20 psig. minus 0 psig.

The 830-RV is not a pop-safety valve and therefore it does not provide full pop-open action but will gradually open on a rising pressure and gradually close on a falling pressure. Upon reseating, bubble-tight closure usually results at 3 to 10 psig. lower than the relieving set pressure depending on whether the set point is extremely high or low.

Of all the challenges you face keeping your customers’ plants operating at full capacity, safety and relief valves shouldn’t be one of them. NASVI’s job is to give you the confidence that your valve supply chain is rock solid regardless the pressure it’s under.
