Vacuum Relief Valve, Side Mount

Model 1360A

Vacuum Relief Valve, Side Mount

The Groth Model 1360A Vacuum Relief Valve is used when vacuum relief is the only requirement. The Model 1360A may be side mounted on the tank body or piped in. Intake relief necessary under working conditions is achieved by a spring or weight loaded pallet in the valve housing. Model 1360A offers Groth’s special “cushioned air” seating. The Model 1360A reduces the possibility of tank damage and provides increased fire protection and safety.
