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.

In a typical globe valve, if the yoke is exposed to the direct flame of a fire, it will expand at a rate much greater than the stem. Thermal effects cause the yoke arms to grow, which makes the disc lift up off the seat, leading to considerable leakage. This is true of virtually all globe valves now on the market.

Conval has developed a simple mechanism that compensates for thermal expansion. The stem bushing is allowed to float in a recess in the top of the yoke and is loaded by a series of Belleville washers. The Bellevilles maintain a load, forcing the stem assembly down into the seat, even when the yoke expands at the high temperatures of a refinery or chemical fire.

The Conval fire-safe Clampseal® valve has been tested and successfully passed the rigorous test procedure defined by the American Petroleum Institute (API) Standard 6FA. In brief, this procedure calls for the test valve to be placed in line and pressurized to 75% of rated pressure, then subjected to a 1400-1800°F fire for 30 minutes. The valve is then quenched with water to cool it to ambient temperature, cycled to prove operability, and then subjected to further pressure testing. The valve is required to maintain strict leakage allowances during and after the burn.

Our entire line of Clampseal® globe valves may be retrofitted with this fire-safe capability, including: Y-pattern stop and stop check valves; T-pattern stop and stop check valves; angle pattern and stop check valves.

In extreme environments, the simpler the design and the fewer the parts, the better. The durable single-piece stainless steel gland contributes to the longevity of the valve.

With secure leak-proof bonnet, this chamber allows rapid access to valve trim for inspection and maintenance. Pressure boundary is sealed at the smallest diameter possible, to ensure maximum strength and low stress.

The Clampseal® pressure-actuated backseat provides maximum valve integrity by ensuring a positive internal stop for the valve stem and disc assembly. The pressure actuated backseat also extends packing life by securely isolating the packing from the pressure when the valve is fully open.

The Axial design ensures tight concentricity, which eliminates side loading of the packing and minimizes wear forces on the trim components. This feature is critical for superior valve performance.

The CLAMPSEAL® Valve is much easier to renew than anything else on the market. The CLAMPSEAL® Valve line provides a modular solution to rising maintenance expenses. Low acquisition cost is not as important as low cost over the serviceable life of a valve. Maintaining a Conval valve is far easier and much less costly than replacing a competitor’s valve.

Curtiss-Wright"s selection of Pressure Relief Valves comes from its outstanding product brands Farris and Target Rock. We endeavor to support the whole life cycle of a facility and continuously provide custom products and technologies. Boasting a reputation for producing high quality, durable products, our collection of Pressure Relief Valves is guaranteed to provide effective and reliable pressure relief.

While some basic components and activations in relieving pressure may differ between the specific types of relief valves, each aims to be 100% effective in keeping your equipment running safely. Our current range includes numerous valve types, from flanged to spring-loaded, threaded to wireless, pilot operated, and much more.

A pressure relief valve is a type of safety valve designed to control the pressure in a vessel. It protects the system and keeps the people operating the device safely in an overpressure event or equipment failure.

A pressure relief valve is designed to withstand a maximum allowable working pressure (MAWP). Once an overpressure event occurs in the system, the pressure relief valve detects pressure beyond its design"s specified capability. The pressure relief valve would then discharge the pressurized fluid or gas to flow from an auxiliary passage out of the system.

Below is an example of one of our pilot operated pressure relief valves in action; the cutaway demonstrates when high pressure is released from the system.

Air pressure relief valves can be applied to a variety of environments and equipment. Pressure relief valves are a safety valve used to keep equipment and the operators safe too. They"re instrumental in applications where proper pressure levels are vital for correct and safe operation. Such as oil and gas, power generation like central heating systems, and multi-phase applications in refining and chemical processing.

At Curtiss-Wright, we provide a range of different pressure relief valves based on two primary operations – spring-loaded and pilot operated. Spring-loaded valves can either be conventional spring-loaded or balanced spring-loaded.

Spring-loaded valves are programmed to open and close via a spring mechanism. They open when the pressure reaches an unacceptable level to release the material inside the vessel. It closes automatically when the pressure is released, and it returns to an average operating level. Spring-loaded safety valves rely on the closing force applied by a spring onto the main seating area. They can also be controlled in numerous ways, such as a remote, control panel, and computer program.

Pilot-operated relief valves operate by combining the primary relieving device (main valve) with self-actuated auxiliary pressure relief valves, also known as the pilot control. This pilot control dictates the opening and closing of the main valve and responds to system pressure. System pressure is fed from the inlet into and through the pilot control and ultimately into the main valve"s dome. In normal operating conditions, system pressure will prevent the main valve from opening.

The valves allow media to flow from an auxiliary passage and out of the system once absolute pressure is reached, whether it is a maximum or minimum level.

When the pressure is below the maximum amount, the pressure differential is slightly positive on the piston"s dome size, which keeps the main valve in the closed position. When system pressure rises and reaches the set point, the pilot will cut off flow to the dome, causing depressurization in the piston"s dome side. The pressure differential has reversed, and the piston will rise, opening the main valve, relieving pressure.

When the process pressure decreases to a specific pressure, the pilot closes, the dome is repressurized, and the main valve closes. The main difference between spring-loaded PRVs and pilot-operated is that a pilot-operated safety valve uses pressure to keep the valve closed.

Pilot-operated relief valves are controlled by hand and are typically opened often through a wheel or similar component. The user opens the valve when the gauge signifies that the system pressure is at an unsafe level; once the valve has opened and the pressure has been released, the operator can shut it by hand again.

Increasing pressure helps to maintain the pilot"s seal. Once the setpoint has been reached, the valve opens. This reduces leakage and fugitive emissions.

At set pressure the valve snaps to full lift. This can be quite violent on large pipes with significant pressure. The pressure has to drop below the set pressure in order for the piston to reseat.

At Curtiss-Wright we also provide solutions for pressure relief valve monitoring. Historically, pressure relief valves have been difficult or impossible to monitor. Our SmartPRV features a 2600 Series pressure relief valve accessorized with a wireless position monitor that alerts plant operators during an overpressure event, including the time and duration.

There are many causes of overpressure, but the most common ones are typically blocked discharge in the system, gas blowby, and fire. Even proper inspection and maintenance will not eliminate the occurrence of leakages. An air pressure relief valve is the only way to ensure a safe environment for the device, its surroundings, and operators.

A PRV and PSV are interchangeable, but there is a difference between the two valves. A pressure release valve gradually opens when experiencing pressure, whereas a pressure safety valve opens suddenly when the pressure hits a certain level of over pressurization. Safety valves can be used manually and are typically used for a permanent shutdown. Air pressure relief valves are used for operational requirements, and they gently release the pressure before it hits the maximum high-pressure point and circulates it back into the system.

Pressure relief valves should be subject to an annual test, one per year. The operator is responsible for carrying out the test, which should be done using an air compressor. It’s imperative to ensure pressure relief valves maintain their effectiveness over time and are checked for signs of corrosion and loss of functionality. Air pressure relief valves should also be checked before their installation, after each fire event, and regularly as decided by the operators.

Direct-acting solenoid valves have a direct connection with the opening and closing armature, whereas pilot-operated valves use of the process fluid to assist in piloting the operation of the valve.

A control valve works by varying the rate of fluid passing through the valve itself. As the valve stem moves, it alters the size of the passage and increases, decreases or holds steady the flow. The opening and closing of the valve is altered whenever the controlled process parameter does not reach the set point.

Control valves are usually at floor level or easily accessible via platforms. They are also located on the same equipment or pipeline as the measurement and downstream or flow measurements.

An industrial relief valve is designed to control or limit surges of pressure in a system, most often in fluid or compressed air system valves. It does so as a form of protection for the system and defending against instrument or equipment failure. They are usually present in clean water industries.

A PRV is often referred to as a pressure relief valve, which is also known as a PSV or pressure safety valve. They are used interchangeably throughout the industry depending on company standards.

Fusible link valves are designed to automatically shut off any gas or liquid in the pipeline when the fire is present. This ensures that fires don’t spread and offers better performance than standard shut-off valves.Heat-sensitive elements will shrink and cause the fusible top work assembly to open, cut off fluid flow through a pipe, and prevent fuel leakage.

The fusible link serves as a pressure release and shutoff valve used to prevent the overpressurization of equipment and/or piping systems. It allows pressurized fluid to discharge through a pipe into the atmosphere or into another section of piping.

A fire-safety valve with a fusible link is an important safety device in the event of a fire on naval vessels, as a fire extinguisher is not sufficient on its own to prevent the risk of explosion from overheating oil tanks.

Fire Safety Valves are critical safety devices designed to isolate flammable liquids and gases from extreme heat and open flames. When exposed to high temperatures, the fire safety valve closes to prevent flammable liquids from coming into contact with heat sources, whether in a fire or an overheated system. These hot shutoff valves are usually available in two configurations: Fire Ball Valves and butterfly valves.

The fire safety ball valve is designed to American Petroleum Institute (API) Standard 607. One of the characteristics of the fire safety ball valve is that it operates under operating conditions similar to ordinary valves. In case of fire, the resilient seat will burn off, but a secondary metal will come into play and allow the ball to seal against it. The valve also includes graphite body seals and packing to prevent external leakage.

A fire safety valve with a fusible connector includes a spring assembly with a clock and a trigger attached to the fusible connector. The connecting Rod keeps the valve open during normal operation by maintaining tension on the spring. When exposed to heat above a certain temperature, the connecting rod disconnects, releasing the Spring and closing the valve.

Fire Safety Valves are essential for all operations from building safety systems to process equipment. THINKTANK provides those fire safety valves to the following applications which have excellent performance. Main Generator and backup generator

For Fire Protection applications, our UL Listed/UL Classified Automatic Control Valves provide reliable high-performance flow control throughout sprinkler systems.

Fire Safe Valves are the valves that has the ability to maintain their pressure holding capacity during and after exposure to fire. The reason for using this kind of valve we use is because of the higher possibility of hazardous/flammable fluid getting leaked from the valves during an event of a fire.

As opined by an expert Valve Stockist in USA,if non-fire safe valves are used for a fluid that is flammable having a higher chance to be exposed to the pool of fire during an accident, then leakage will occur from the valve stem seal that already might have melt. Thus, as suggested a need for a fire-safe valve that doesn’t leak when exposed to fire is the need of the hour.

There are actually two kinds of leak that is supposed to be avoided when a valve is exposed to a fire accident which leads to leakage from the stem and leakage from the seat. Owing to this there are two distinct methods to achieve a fire-safe design, as formulated by expert Valve Manufacturersby the usage of a fire-proof component or by use of a non-fire proof component which is supported by a special design that prevents leakage after the components melt in case of a fire mishap.

Fire safety valves being a recent development in the industrial tools to prevent fire are basically designed to prevent a fire from spreading if the fuel valve gets damaged causing a leakage.

Actually these valves are spring-loaded valves that are thermally actuated which in case of fire, close automatically stopping the fuel flow from the crankcase of the engine thus the reserve oil supply gets stopped, minimizing the chances of leakage occurring.

The benefits of using these valves are the protection of human lives, lowered insurance rates, and the protection of equipments along with the buildings it is placed.

Under the scorching high temperatures, it is necessary to use metal construction for the valves, the reasons why the primary valve types to be considered for fire-safe are gate and globe valves because of their metal-to-metal seating.

The soft-seated rotary valves include the ball valves, plug valves and butterfly valves. All the manufacturers of rotary stem valves in order to prove bubble-tight shutoff in the normal valve operation as well as fire safety are employing two types of valve seating arrangements.

Here in the first system, for the fire-safe ball valves,a metal sealing usually occurs when, the floating ball moves downstream to contact a machined surface in the body which matches the shape of the ball.

The second system typically used by some of the high-performing butterfly valve supplier and manufacturers is not wholly depending on the total seat burn since a resilient seat and metal seat primarily contacts the disc at the same point of time.

If the valves are of a two/ three-piece body design, then utmost attention must be paid to the body seal materials to prevent a worst leakage during a fire accident. The butterfly valves generally use a rigid disc and a stem connection where the packing material is graphite due to its ability to withstand higher temperatures of 700°C). The one-piece body design of all most all of the high-performance valves ensure to eliminate body seal leakage efficiently.

Our fire safe valves are ball valves and butterfly valves availabe for a maximum custom configuration. As a leading Valve Stockist in UAE, we ensure that our valves are available in all sizes. All fire safe valves are UL FM approved valves that have a higher temperature range.
