Product Overview

The Groth Model 12F-TWW-0 Pressure/Vaccum Relief Valve with Pipe-Away design was crafted to exceed the typical industry needs. Through comprehensive research and development, Groth has developed and produced a product able to achieve both superior sealing performance as well as industry-leading flow rates. And it’s able to do all of this while reducing the valve size and utilizing 10% overpressure technology, allowing customers to reach necessary flow rates. Further, the pressure vacuum relief valve component is designed to protect your tanks from potential damage associated with overpressure or excessive vacuum. It is also able to reduce the costly product evaporative losses associated with normal tank “breathing,” adding further value for end-users. The 12F-TWW-0 model is a superior sealing valve able to minimize fugitive emissions while also providing increased protection and safety to tank equipment and on-site personnel.
