Pressure relief valves for air compressor systems are simple, spring-loaded mechanisms. When the inlet pressure force is greater than the spring load, the safety valve opens in proportion to the increase in pressure and allows air to “leak out” as needed. WebPressure Relief Valve - is the term used to describe relief device on a liquid filled vessel. For such a valve the opening is proportional to increase in the vessel pressure.
