Groth Corporation Relief Valves
Pressure / Vacuum Relief Valve With Pressure Spring MODEL 1201B

Pressure / Vacuum Relief Valve With Pressure Spring MODEL 1201B
The 1200 series is designed to protect your tank from damage created by overpressure or excessive vacuum. Costly product evaporation losses due to normal tank “breathing” are greatly reduced. Because the valve retains toxic vapors, atmospheric contamination is minimized. This helps to provide increased fire protection and safety. The 1201B Pressure/Vacuum Relief Valve is a spring-loaded version of the 1200A PVRV for use at pressures of 1 PSIG and above.

Peripheral and central seat guides ensure reliable, repeatable performance
A wide seat and air-cushion seal keeps leakage low long after the valve is put in service
Self-draining housing body and drip rings protect seating surfaces from condensate and freezing, increasing operational reliability
Fluoropolymer seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture
