WebThere are two main types of pressure relief valves / safety valves: Spring-loaded pressure relief valves and pilot-operated pressure relief valves / safety valves. Also relevant are so-called change-over valves, which ensure continuous system availability.. Pilot operated pressure relief valves (POSV = “pilot operated safety valves”) are controlled by the process … WebA conventional PSV uses a spring to set the pressure at which the PSV's relieves at. When the pressure builds up to the set point, the spring will then compress and allow the gas or fluid to pass. As the pressure decreases below the set point, the pressure expands stopping the flow from relieving.
