Vacuum Relief Valve, Top Mount

The Groth Models 1300A & 1301A are used when vacuum relief is the only requirement. Intake relief necessary under working conditions is achieved by a spring or weight loaded pallet. This feature reduces the possibility of tank damage due to an excessive vacuum condition. Valve size must be selected to perform required vacuum relief under operating and thermal conditions.
