Description
Pressure/Vacuum Relief Valve Vent to Atmosphere
Model: 12E-TWW-0
Description
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.
Features
This valve is designed to utilize 10% overpressure technology
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
