Weight Loaded Vacuum Relief Valve

The Groth Model 13T-T0W-0 weight loaded vacuum relief valve is designed to be
used in applications where additional vacuum relief is necessary. Intake relief necessary
under working conditions is achieved by a weight loaded pallet. The 13T-T0W-0
helps to provide increased fire protection and safety. Valve size must be selected to
perform required vacuum relief under operating and thermal conditions.


• Product leakage and fugitive emissions are reduced via ultra-tight sealing
• Higher flow capacity to protect from excessive vacuum build up
• Peripheral and central seat guides ensure reliable, repeatable performance
• Designed for easy maintenance, thus reducing downtime and operational cost
