A pressure-relieving device that automatically opens to prevent a pressure system from exceeding its allowable pressure.
A Pressure Relief Valve (PRV) is an automatic pressure-relieving device designed to open at a predetermined pressure to protect pressure-retaining equipment from overpressure. PRVs may be used with compressible or incompressible fluids and are selected according to the service conditions, applicable engineering codes and required relief characteristics.
Pressure Relief Valves protect pressure systems by automatically relieving excess pressure before equipment limits are exceeded.
Pressure Relief Valves are an essential component of overpressure protection systems and are designed, sized and installed in accordance with applicable engineering codes and standards.
A Pressure Relief Valve is the general class of automatic pressure-relieving device, whereas a Pressure Safety Valve is a specific type of pressure relief valve designed primarily for compressible fluid service.
