An auxiliary passage, which is where the relief valve sends the extra liquid or gas to relive the pressure in a mechanism, is usually just an extra pipe that leads to a chamber where most likely the fluid is burned and the gas left over is released into the atmosphere. This is a particular necessity in the chemical and petrochemical manufacturing industry, as well as in petroleum refining plants, natural gas processing and power generation industries.

If the pressure in a hydraulic pump exceeds its designed pressure limit, internal leakage or damage to the pump components can occur. Depending on what the liquid is, such leaks could also cause serious damage to individuals in the vicinity and the environment.

In hydraulic control systems, the relief valve acts as a check valve, with a ball and an adjustable spring. When a relief valve opens to divert fluid into an auxiliary passage, the pressure inside the hydraulic cylinder drops and allows the valve to close. A hydraulic system will often employ several types of valves, although the hydraulic relief valve is usually the first encountered in the circuit.

Hydraulic relief valves can be found in almost any mechanism that runs on hydraulic power, such as automobile transmissions, brakes, power steering, aviation and in industrial and construction machinery. Relief valves are built from the same basic materials that most hydraulic valves are made from. The strong and corrosion resistant metals that are most common are stainless steel, aluminum, iron, brass and copper.

Aluminum and stainless steel are thin, light weight and flexible, while still retaining the strength necessary to control the flow of liquid. Usually when a heavy metal like iron is used for the body of a valve, one of those two lighter metals is still used for the disc or plunger.

Plastic is also used, particularly thermoplastics that are developed specifically to be used as valve material. Although they are not as resistant to corrosion as metal, they are cheaper. It"s all about options.

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.

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.

The pilot is designed to open gradually, so that less of the system fluid is lost during each relief event. The piston lifts in proportion to the overpressure.

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.

Hydraulic valves are used to direct and control the flow of fluids through a system of pipes, hoses, or cylinders, converting the fluid force into mechanical energy. This energy is transmitted through the hydraulic system by a series of accumulators, pumps and actuators to operate a wide range of equipment for a vast array of functions. They are generally part of a "closed loop" system with a reservoir, that allows the fluid to expend its driving force before being returned to the reservoir for continuous function.

In Ancient Greece, Aristotle noted that water is a continuum. A century later, Archimedes stated that a body in water floats due to the force of displacement and that pressure gradient is an essential part of flow. Leonardo DaVinci developed the first mathematical flow formula at the turn of the sixteenth century, and designed the first known closed loop control system to regulate the flow rate of water to a water wheel.

All of these grounding theories were pertinent to the advancement of hydrostatics (water at rest) and hydrodynamics (water in motion), paving the way for hydraulic (water powered) developments.

In 1648, Frenchman Blaise Pascal presented the Hydrostatic Transmission Theory claiming that pressure applied to a static fluid is transmitted equally in all directions. Now known as Pascal"s Law, this theory is the fundamental basis of hydraulics.

Joseph Bramah patented the first hydraulic machine in 1795. It was an industrial press with designs still in use. His progress was followed by the likes of Robert Boyle, Sir Isaac Newton, Daniel Bernoulli, and Leonhard Euler, all of whom lent their knowledge to the field of hydraulics.

Around 1907, Harvey Williams and Reynolds Janney developed the first axial piston devices, which were both pumps and motors, that used the fluid medium as a lubricant. Water was not an adequate medium, so oil hydraulics came into existence, nearly obliterating the water hydraulic industry.

In 1956, a misplaced mining wagon ruptured a hydraulic oil line and severed an electrical line at a mine in Belgium. The ensuing fire killed 262 people, inciting new legislation that required mines and manufacturers to use water hydraulics for safety reasons. These systems are still considered a safe, effective alternative to oil hydraulics. Both systems are in use today.

Most hydraulic valves are made from iron, brass, steel, or stainless steel. Smaller units may be made from plastics. The seat, or outer housing of a valve, and the body, or inner component that opens and closes the channel, may be cast, die forged, or machined. An external wheel or lever is incorporated with the body to operate it.

Basic hydraulic valves have two stations: open and closed. When closed, no fluid is able to pass through but when open, it flows freely. Hydraulic valves are used within a fluid control system as a simple way to prevent improper levels of pressure and fluid. The simplest hydraulic valve uses two equally sized pistons in two cylinders connected by a pipe filled with hydraulic fluid. When force is applied to one piston, the other rises. Because the fluid can not be made smaller, it is considered incompressible, and may only be displaced. This means that the pipe containing the hydraulic fluid may be any size, shape, or configuration. As long as it is full and no compressible air bubbles are present, pressure applied at one end will result in virtually equal force at the other end.

Hydraulic power transmission is very effective. It may be divided through the use of a manifold and subsequent slave cylinders that are operated by a master cylinder. The most prevalent example of this is the braking system on an automobile. One pedal operates the brakes on all four wheels at the same time.

The force at the business end of a hydraulic valve may be "stepped up" or "stepped down" by changing the size of one piston and cylinder in a process of hydraulic multiplication or division. For example: a two inch diameter cylinder with a nine inch long piston will raise another two inch diameter piston nine inches with an applied force of one hundred pounds.

If the second piston has a diameter of six inches, it has a surface area nine times larger than the two inch piston. The smaller piston will only move the larger piston one inch in distance, but the resulting force is multiplied by nine, providing nine hundred pounds of pressure from one hundred pounds of initial force. Mathematical formulas may be applied to calculate accurate valve sizes and configurations for any hydraulic system.

Some valves shut off flow when flow rates get too high, while others transmit signals to other valves in order to provide a systematic balance of flow. These valves protect hydraulic systems from being exposed to high pressures that exceed the mechanism"s specified limits. The solenoid converts electrical energy into mechanical energy. When the wire coil receives a current, a magnetic field acts upon the plunger, which results in opening or closing of the valve. Hydraulic check valves have two openings: an inlet in which the fluid enters and an outlet through which the fluid exits. They prevent backflow. Hydraulic directional control valves permit flow in more than one direction because they have a component that shifts or rotates to line up with the corresponding pipes or tubes and accommodate a number of ports. Hydraulic control valves prevent improper levels of pressure and fluid in hydraulic systems. Hydraulic relief valves are used to limit the pressure in a hydraulic system by allowing the pressurized hydraulic fluid to flow out of the system into an auxiliary passage. Protecting the passage of the substance as well as the environment through which it is passing is the overall goal of hydraulic valves, as well as protecting the substance and its source.

The type of hydraulic control valve placed in the system will depend on the specifications of the job. Some valves such as ball valves, butterfly valves, globe valves, check valves, and gate valves are simple flow control valves that are generally either fully open or completely shut.

Parts that control the flow and pressure of a fluid by using a spherical element to create a seal. Ball valves are used in critical high pressure applications that require a quick and easy shutoff.

Used to contain and transfer the flow and pressure of hydraulic fluid in hydraulic systems. There are many different designs of hydraulic control valves, including check, cartridge, directional, relief, safety, shut off, and hydraulic solenoid valves. Hydraulic control valves come in a variety of sizes and pressure ratings.

Control the direction of the hydraulic fluid to the point where it is needed. Directional control valves are useful for hydraulic tools and farm equipment that use hydraulics.

Valves that automatically open or close as the liquid level changes. Float valves are operated mechanically by a float that rests on top of the liquid.

Linear motion valves in which a flat closure element slides into the flow stream to provide shut-off. Gate valves are designed to minimize pressure drop in fully open positions.

Multi-turn valves that have a closing element that moves perpendicular to the valve body seat and generally seals in a plane parallel to the direction of flow. This type of valve is suited both for throttling and general flow control.

Devices that regulate fluid flow between components in a hydraulic system. They let an operator know how much fluid is flowing between the pump and actuators, the hydraulic devices that move or control a mechanism.

Have small ports with thin threaded plungers that allow for tight flow regulation in hydraulic systems. Though the flow rates are low, needle valves provide a steady and precise flow of fluid and are therefore used for calibration or flow regulating applications.

Also known as a directional valve or directional control valve, is used as a switching device to control hydraulic equipment. It blocks and opens fluid pathways inside the valve to activate power transmission. It is a cylinder with a cutaway view resembling a thread spool, sealed inside a casing. Valves on one side lead to a pump and storage tank. Other valves may lead to a single device, or to a hydraulic manifold which directs power to multiple devices. The controller moves the spool into different positions, moving the fluid through the system. Pressure flows either from the pump to the devices or from the devices back into the fluid reservoir, but only provides force in one direction, depending on the position of the spool, which determines whether the force pushes or pulls.

Regulates the output pressure in a system with multiple hydraulic lines. Commonly found as components of braking systems for cars, p valves provide less pressure to rear brakes to keep them from locking up.

An electromechanical valve. An electrical current is run through a coil which creates a magnetic field. This causes a plunger to open or close the valve. Solenoid valves may be direct-acting, in which case the plunger opens and closes an internal orifice directly, or they may be pilot-operated, also known as servo-type valves, wherein the plunger operates a pilot orifice. Fluid pressure in the line passing through the pilot orifice operates the valve seal. Most s valves have an inlet port and an outlet port, classifying them as two port valves, although they may be designed with more outlet ports. Because they are controlled with electricity, they can be computer programmed to operate systems automatically.

Also known as logic valves and 2/2 valves, are threaded inserts that screw into a cavity in a manifold or a valve body. They may be used to control flow rate, direction, or pressure.

Directional control valves that only allow hydraulic fluids to flow one way. They are two port valves, meaning they have one inlet and one outlet, that are opened by the pressure of the fluid flow within, and shut by any backpressure that flows back into the pipe.

Types of safety valves designed to release pressure once it has built to a specific point. In equipment operation, hydraulic relief valves will relieve pressure by sending excess hydraulic fluid back to the storage tank. These valves may be pressure activated or spring loaded. Commonly found on water heaters, a safety relief valve will vent steam if the water in the tank gets too hot.

A type of pressure relief valve that are easily identified by their rapid opening and closing, which is directly proportional to increases in pressure.

Hydraulic valves are used in cars to actuate brakes, clutches, and gears. They are used in engine lubrication and air conditioning systems. Some car jacks use hydraulic cylinders to provide lift. The Jaws of Life utilize a system of hydraulic piston rods that can cut, spread, push, or pull a vehicle apart to rescue passengers.

Some hydraulic valves can handle several thousands of pounds per square inch of pressure and are found in heavy equipment operation. They control dump beds on trucks, swing arms on backhoes, blade adjustments on graders, track drives, conveyors, scissor lifts, and forklifts. Hydraulic valves are found in all industrial timber cutting and processing equipment, water and sewage treatment facilities, power plants, mining operations, oil, gas, and petroleum works, food harvesting, processing, and packaging operations, chemical processing plants, and plastics manufacturing.

Hydraulic control valves can be used to operate tiny nano-bots that perform microsurgery with masterful precision as easily as they control crane booms that can lift railroad cars or place construction materials on catwalks hundreds of feet in the air. They are at the heart of manufacturing automation and robotics. Without hydraulic components, there would be no amusement parks or draw bridges, and many industries would be reduced to a crippling crawl.

One of the simplest hydraulic devices is the log splitter. It is driven by an engine, typically a four-stroke gas motor, attached to an oil pump. The pump pushes the oil into a spool valve that operates a ram. The spool valve moves fluid into the ram with "stepped up" force. The ram of the log splitter is a hydraulic cylinder, with a wedge at the head, which splits the wood as the operator applies pressure to the lever. A reservoir contains hydraulic oil. It is often equipped with a filter to maintain the cleanliness of the oil.

A gear pump is the most common type of pump found in hydraulic systems. It is a positive displacement pump and is used to move high-viscosity fluids continuously. The gears are housed inside the pump casing and are classified as external or internal depending on the configuration. Gear pumps use two spur gears that mesh together. One of the gears is driven by a motor, the other, called an idler, is driven by the first gear. The counter-rotation creates a void in the intake side, suctioning hydraulic fluid into the rotation and moving it out the exhaust port. Tight tolerances between gears prevent backflow.

The ram is a piston rod that is driven by the fluid being pumped through the spool valve. In the log splitter, the pump pushes oil against the ram, which applies increasing pressure to the log, until it splits. The lever is released, the oil returns to the accumulator, and the process may begin again.

In heavy equipment, a series of pumps and rams are inter-connected through hydraulic lines to perform heavy duty moving, lifting, digging, and farming. These same tools on a miniaturized scale can be trusted to perform delicate brain or eye surgery. The valves that operate multiple component systems can be computer controlled for accuracy and automation.

Wear gloves and safety glasses. Hydraulic fluids often contain chemicals that can irritate skin and eyes. A pinhole leak in the system can spray oil at very high pressure, injecting the oil into the skin. Accidental ingestion can cause grave illness.

Watch out for the environment. Conventional hydraulic oil is not environmentally friendly. There are options available that are. If alternatives don"t work for specific applications, make sure to handle the fluids responsibly.

The static pressure existing at the outlet of the relief device at the time the device is required to operate. It is a result of the pressure in the discharge system coming from another source. May be constant or variable.
