Pressure Relief Valves RS Components

Pressure relief valves operate in a similar manner to pressure safety valves, and the two terms are sometimes used interchangeably. However, the key difference is that PRVs operate gradually to regulate pressure, while PSVs operate very quickly to counteract sudden pressure spikes. To this end PRVs are more commonly used in liquid systems, and PSVs are more commonly used in gas systems.
