Description
The Groth 1300A Series is used when vacuum relief is the only requirement. The necessary inbreathing relief 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. The 1300A Series helps provide greater fire protection and safety. The valve size must be selected to meet the required vacuum relief under operating and thermal conditions.
