Model: 2450A
Description
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.
Features
A wide stainless steel seat and air-cushion seal
