Sizing Pressure-Relief Devices

2013-11-4 · The set pressure of a relief device is the pressure at which the device operates. For spring-operated relief valves, small amounts of leakage start to occur at 92–95% of the set pressure. A relief device''s overpressure is the pressure increase over its set pressure, usually expressed as a percentage of the set pressure.
