Pressure Relief Valves allow a tank to vent (breathe out) during filling, emptying and when thermal effects require.

Spring/Weight Operated Pressure Relief Valves

Pressure Relief ValveKey Features of our Pressure Relief Valve include;

 

  • Self Draining Pallets prevent the build-up of water and potential to freeze shut/open
  • There are no elastomers in Groth valves as they break down over time in common applications

Pilot-Operated Pressure Relief Valves (PORV)

Pilot operated pressure relief valvesPilot operated pressure relief valves allow a tank to vent (breathe-out) during filling and when thermal effects require, but with much higher pressure settings than a weighted or spring-loaded valve.

Key Features of the Groth Pilot Operated Pressure Relief Valve include;

  • High Flow Capacity
  • Bubble tight to set pressure
  • Fully open at less than 10% above the set pressure
  • Inherent backflow prevention
  • Easily adjustable blowdown
  • Film design seat meets EPA method 21
  • Full pipe bore seat nozzle

As with all Groth equipment, their Pilot Operated Pressure Relief valves are manufactured to the highest standards and offer market-leading performance and longevity.
