Sizing Pressure-Relief Devices
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.

Pressure Relief Valve Installation and Operation Guide
Pressure Relief Valve Operation. Avoid operating the valve too close to the set point. Doing this can cause simmer and leakage. Once this starts, it will only get worse. Avoid testing your valve too often. Lifting the test lever too often can allow dirt or other foreign matter to get into the seat, which can cause the valve to leak.
