The set point of a pressure relief valve is typically determined by the MAWP. The set point of the relief device should be set at or below this point. When the pressure relief valve to be used has a set pressure below 30 psig, the ASME Code specifies a maximum allowable overpressure of 3 psi.

SAFETY AND SAFETY RELIEF VALVES FOR STEAM SERVICE Vessels or other pressure-containing equipment that operates filled with liquid must be provided with liquid-relief valves, unless protected otherwise [1]. Any liquid-relief valve must be at least 0.5 in.
