VRV Series Vent Relief Valve
Brand: Generant Inc
A compact, highly accurate, direct acting pressure relief valve. Factory preset to desired crack pressure and/or flow specifications.
Internal adjustment provides tamper proof safety against inadvertent pressure changes. Available vent to atmosphere or inline configurations in brass, aluminum and 316 stainless steel.
Valves feature a Quad ring seal which provides for extreme accuracy and repeatability with a narrow reseal band. Optional deflector cap increases flow capacity and provides for deflection of discharge.
Features- Accurate and repeatable cracking pressure
- 100% factory preset and tested
- Zero leakage to 95-98% of set pressure
- Tamper proof adjustment
- Excellent reseal performance
- Compact size
