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 their required flow rates with a potentially smaller sized valve and utilize 10% overpressure technology. The Model 12F-TWW-0 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.
Features & Benefits
This valve is designed to work with a 10% overpressure.
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.
