In steam boiler applications, pressure relief valves (PRVs) are the silent sentinels — the last line of defense against potentially disastrous overpressure situations. In a perfect world, boiler ...

1. A pressure relief valve (PRV) protects equipment by automatically opening to vent process media when the pressure in the inlet nozzle overcomes the downward force of the spring.

“Pressure relief valves positioned on either the suction or discharge sides are not notably distinct, aside from their designated pressure ratings,” said Aschow. “Currently, there exists a substantial ...
