Key Features of our Pressure Relief Valve include;

• Market-leading sealing performance – API2000 states that a valve should hold 75% of its set point at the constant flow of 15l / hour – Groth’s production standard is 90% in models up to and including 6”

• Self Draining Pallets prevent the build-up of water and potential to freeze shut/open

• Air cushion seat design creates a superior seal and is less prone to sticking than o-ring type seals

• There are no elastomers in Groth valves as they break down over time in common applications

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

Groth Pressure Relief valves come with a range of standard and custom options as follows;

Pilot 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
