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 helps protects the tank against rupture or internal pressures caused by fire exposure and other emergency events. Model 2400A is designed to be self-closing, while Groth’s special fluoropolymer “cushioned air” pallet and peripheral guiding insures proper alignment and integrity of seating. The valve can be offered in corrosion resistant materials throughout.
