MODEL 12F-TSW

Spring Loaded Pressure / Vacuum Relief Valve – Pipe Away

The Groth Models 12F-TSW PVRV 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 & 12F-TSW are superior sealing valves developed to minimize fugitive emissions while providing increased protection and safety to tank equipment and on-site personnel.
