A spring-loaded pressure relief valve designed primarily to protect pressure systems handling compressible fluids.
A Pressure Safety Valve (PSV) is a spring-loaded pressure relief valve designed to open rapidly at a predetermined set pressure to protect pressure vessels and piping systems handling compressible fluids such as steam or gas. It automatically reseats after system pressure has returned to an acceptable level, preventing equipment from exceeding its allowable pressure limits.
Pressure Safety Valves provide rapid overpressure protection for pressure systems handling compressible fluids.
PSVs are widely used in accordance with ASME, API and ISO pressure equipment standards and form a critical component of process safety and overpressure protection systems.
A Pressure Safety Valve is a specific type of pressure relief valve used primarily for compressible fluids, whereas Pressure Relief Valve is the broader term encompassing several types of pressure-relieving devices.
