- Pressure/Vacuum Relief Valve with Pressure Spring 1201B-02-555-T00 Groth Vietnam Model 1201B Pressure/Vacuum Relief Valve with Pressure Spring 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.
