Pressure Relief Valves

Our pressure relief valves are designed to protect industrial piping systems and vessels from over-pressurization. These valves open when there\'s an increase from the set pressure, and close when the level drops before the set pressure.

Three functional elements of a HVAC pressure relief valve:

  • Valve element – typically a spring-loaded poppet valve
  • Sensing element – a piston or a diaphragm
  • Reference force element – usually a spring

 

When selecting a pressure relief valve, special care should be taken. We at Evergreen recommend customers browse through our stock of atmospheric pressure relief valves, straight through pressure relief valves, & female connection pressure relief valves to select the type that best serves your specific purpose.
