WebA relief valve or pressure relief valve ( PRV) is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, … Webed relief valve. HIGH INLET PRESSURE DROP When the length of pipe leading to the inlet of the PRV causes an excessive pressure drop to a level below its reseat pressure, the valve will begin to oscil-late open and closed, potentially leading to chatter. This situation can lead to bel-lows failure caused by premature fatigue.
