Emergency Relief Valves

Model 2000A
Emergency Pressure Relief Valve

The Groth Model 2000A 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. Removable stops can be provided which restrict the lift of the cover.

              • Grounding Cable connects the head and flange
              • Cushioned Air pallet
              • Peripheral Guiding

Model 2100
Emergency Pressure Relief Valve - Spring loaded

The Groth Model 2100 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 pressure. Model 2100 relieves, then reseats when the overpressure event has been dissipated.

              • Easy access manway combined with emergency relief
              • Independently adjustable springs keep the valve tightly sealed until set pressure is reached
              • FKM seating ensures a tight seal

Model 2400A
Emergency Pressure Relief Valve - Weight loaded with hinge

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. ┬áThe valve can be offered in corrosion resistant materials throughout.

              • A wide stainless steel seat and air-cushion seal keeps leakage low long after the valve
                is put in service
              • A hinged design including a lift stop ensuring positive re-seating for reliable performance
              • Easy access manway combined with emergency relief

Model 2050A
Emergency Pressure and Vacuum Relief Valve - Weight loaded

The Groth Model 2050A Emergency Pressure Vacuum Relief Valve is designed to provide emergency relief capacity beyond that furnished by the normal operating pressure or vacuum relief valves on the tank. The Model 2050A valve protects the tank against rupture, explosion or implosion that could result from excessive internal pressures or vacuum conditions caused by fire or rapid emptying of the tank. As excessive pressure builds up, Model 2050A relieves, then re-seats when overpressure has been dissipated.

              • Built of corrosion resistant materials
              • Grounding Cable connects the head and flange
              • Cushioned Air pallet
              • Peripheral Guiding
              • Vacuum breaker

Model 2450A
Emergency Pressure and Vacuum Relief Valve - Weight loaded with Hinge

The Groth Model 2450A Emergency Pressure Vacuum Relief Valve is designed to provide emergency relief capacity beyond that furnished by the normal operating pressure/vacuum relief valve on the tank. The valve protects the tank against rupture or excessive internal pressures caused by fire exposure, etc. The valve is designed to be self-closing. As excessive pressure builds up, it relieves, then reseats when over pressure has been dissipated. Model 2450A is built of corrosion resistant materials throughout. Groth’s special fluoropolymer “cushioned air” pallet and peripheral guiding ensures proper alignment and integrity of seating.

              • A wide stainless steel seat and air-cushion seal
