Pressure Relief Valve Engineering Handbook

Pressure Safety Valve Testing. A pressure safety valve (PSV) protects pressure vessels and piping systems from excessive internal pressure. When a system reaches a predetermined pressure the PSV opens, a portion of the media discharges, and the pressure inside drops to a safe limit. Once the pressure reaches the valve's reseating set point
