Vacuum Relief Valves
Pressure relief valves are used to maintain near atmospheric or low vacuum conditions within a vessel whilst minimising exposure to atmosphere.
Vacuum and Tank Equipment
Model 13S-TOW
Groth Vacuum Relief Valve (VRV) - Weight Loaded, Horizontal Mounted
The new 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.
- 10% Overpressure Advantage - Full rated flow capacity achieved at 10% over-pressure
- 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
- Compliant to API-2000 and ISO 28300 standards
Model 13T-TOW
Groth Vacuum Relief Valve (VRV) - Weight Loaded, Top Mounted
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.

Model 1300A
Groth Vacuum Relief Valve
The Groth Series 1300A is 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. The 1300A Series helps to provide increased fire protection and safety. Valve size must be selected to perform required vacuum relief under operating and thermal conditions.
- Modular Construction
- Cushioned air seating
- Fluoropolymer seating diaphragms minimize sticking caused by resinous vapors and atmospheric moisture
- Self-draining housing body and drip rings to protect seating surfaces from condensate and freezing
- Design avoids vacuum buildup due to binding or clogging of the vent
- Compliant to API-2000 and ISO 28300 standards
Model 1360A
Groth Pressure Relief Valve - Side Mount
The Groth Model 1360A Vacuum Relief Valve is used when vacuum relief is the only requirement. The 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. The 1360A helps to provide increased fire protection and safety. Valve size must be selected to perform required vacuum relief under operating and thermal conditions.

Model 1361A
Groth Pressure Relief Valve
The Groth Models 1361A 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.
