Description
The Groth Model 2500A Pilot-Operated 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 an external fire, etc. Model 2500A is designed to be self-closing. As excessive pressure builds up, Model 2500A relieves, then reseats when overpressure has been dissipated.
