partially open). A valve is required to open at 500 psig inservice where the service temperature is 400° F, and back pressure = 25 psig. Differential set pressure = 500 psig – 25 psig = 475 psig. Temperature multiplier: 1.013. Cold differential test pressure = 475 psig x 1.013 = 481 psig. The set pressure of a relief device is the pressure at which the device operates.

In case of high pressure pumps, it is better to set the pressure at 10 - 12 % above the system's working pressure. For low pressure puumps the operating pressure of PRV can be set below the maximum discharge pressure of pump but above the system's working pressure. A good judgement is needed to determine the PRV pressure setting. Regards. Our experience shows that between 75% and 85% of PRV performance issues—including leaks, chattering (rapid opening and closing), failure to open at designated set pressure, long blowdown (closing too far below set pressure) and short uptime between repairs—can be attributed to improper system design, incorrect valve installation, poor maintenance practices, or a combination of these factors. Set pressure must be demonstrated first and then pressure is again lowered. Then the inlet pressure is raised to 90% of set pressure (hold pressure is 0.34 barg below set pressure if set pressure is lower than 3.44 barg) and needs to be held at 90% for all sizes for 1 minute.

Relieving pressure (PR) - This is the pressure at which the full capacity of the safety valve is achieved.

For spring-operated relief valves, small amounts of leakage start to occur at 92–95% of the set pressure.
