Vacuum Relief Valves (VRV)

Key Features of the Groth Vacuum 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 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 Vacuum Relief Valves are manufactured to the highest standards and offer market-leading performance and longevity.

Groths Vacuum Relief Valves come with a range of standard and custom options as follows;

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