Weight Loaded Vacuum Relief Valve

The Groth Model 13S-T0W-0 is used when vacuum relief is the only requirement. The
13S-T0W-0 is side mounted on the tank body or piped in. Intake relief necessary under
working conditions is achieved by a 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.


• This valve is designed to utilize 10% overpressure technology
• 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
