The Groth Model 12E-TWW-0 Pressure/Vacuum Relief Valve that vents to atmosphere design was created to exceed industry needs. Extensive research and development has produced a product that achieves both superior sealing performance and industry leading flow rates, while also allowing customers to reach their required flow rates with a potentially smaller sized valve and utilize 10% overpressure technology. Costly product evaporative losses due to normal tank “breathing” are greatly reduced. The Model 12E-TWW-0 are superior sealing valves developed to minimize fugitive emissions while providing increased protection and safety to tank equipment and on-site personnel.
