A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire. The pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system. The relief valve is designed or set to open at a ...

Balanced relief valves are spring-loaded valves that contain a bellows arrangement to keep back-pressure from affecting the set point. Figure 13-4 shows a cross section of a balanced relief valve, and Figure 13-5 is a schematic that shows how the valve operates. The bonnet is vented to atmosphere and a bellows is installed so that the back-pressure acts both downward and upward on the same ...

the pressure relief valve, therefore, is the process fluid. Once a condition occurs that causes the pressure in a system or vessel to increase to a dangerous level, the pressure relief valve may be the only device remaining to prevent a catastrophic failure. Since reliability is directly related to the complexity of the device, it is important that

Noun 1. relief valve - a valve in a container in which pressure can build up ; it opens automatically when the pressure reaches a dangerous level escape...

Pressure Relief Valves. A pressure Relief Valve is a safety device designed to protect a pressurized vessel or system during an overpressure event. An overpressure event refers to any condition which would cause pressure in a vessel or system to increase beyond the specified design pressure or maximum allowable working pressure (MAWP).

Thermal relief valves are installed in sections of the system in which fluid can be trapped, usually in the lines between the selector valves and the actuators. When fluid in these lines absorbs heat and expands, the thermal relief valve momentarily unseats and releases enough fluid back into the system return manifold to relieve the high ...

Thermal Relief Valves for Filter Vessels. When filter vessels are manufactured they are designed at a set pressure and undergo strict approval processes. It is therefore vital that any excess pressure build up needs to be removed from the system quickly and safely. One of the main causes of pressure increase is thermal expansion from hot ...

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. The following types of safety valve are defined in the DIN 3320 standard, which relates to safety valves sold in Germany and other parts of Europe:

Thermal relief valve—the pressure relief valve is used to relieve excessive pressures that may exist due to thermal expansion of the fluid. They are used where a check valve or selector valve prevents pressure from being relieved through the main system relief valve. Thermal relief valves are usually smaller than system relief valves.

Advantages of conventional relief valves are reliability and versatility. These relief valves are most reliable when sized properly and can be used in a wide range of services. Disadvantage of these relief valves is the effect of backpressure on the relieving pressure of valve and hence pressure accumulation in the protected equipment.
