Emergency Pressure Relief Valve, Weight-Loaded; Hinged

The Groth Model 2400A 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 internal pressures caused by fire exposure, etc. Model 2400A is designed to be self-closing. As excessive pressure builds up, it relieves, then re-seats when overpressure has been dissipated. The valve is built of corrosion resistant materials throughout. Groth’s special fluoropolymer “cushioned air” pallet and peripheral guiding insures proper alignment and integrity of seating.
