Emergency Pressure Vacuum Relief Valve, Weight-Loaded

The Groth Model 2000A Emergency Pressure Relief Valve is designed to provide emergency relief capacity beyond that furnished by the normal operating pressure relief valve on the tank. The valve protects the tank against rupture or explosion that could result from excessive internal pressures caused by fire, etc. As excessive pressure builds up, Model 2000A relieves, then re-seats when overpressure has been dissipated.
