Groth Pressure and Vacuum Relief Valve (PVRV) with atmospheric venting – Conservation Valve

Pressure settings: 1 to 15 psi ( 69 to 1034 mbar)
Vacuum settings: below 1.5 psi (103 mbar)

The new Groth Model 12E-TSW spring loaded design was created to exceed industry needs. Extensive research and development have produced a product that achieves both superior sealing performance and industry leading flow rates, while also allowing customers to reach required flow with a potentially smaller sized valve. The pressure/vacuum relief valve is designed to protect your tank from damage created by
overpressure or excessive vacuum. Costly product evaporative losses due to normal tank “breathing” are greatly reduced. The Models 12E-TSW is a superior sealing valves developed to minimize fugitive emissions while providing increased protection and safety to tank equipment and on-site personnel.

• Utilizes the latest 10% overpressure technology for full lift in+10% of the setpoint.
• Product leakage and fugitive emissions are reduced via ultra-tight sealing
• Higher flow capacity to protect from both excessive pressure and excessive vacuum build up
• Peripheral and central seat guides ensure reliable, repeatable performance
• Designed for easy maintenance, thus reducing downtime and operational cost
• Superior tightness, exceeding API-2000 leak requirements
• Compliant to API-2000 and ISO 28300 standards
