BREATHER VALVE W/ FLAME ARRESTOR – TVFA
TVFA Breather Valve with Flame Arrestor – A Safe Solution for Storage Tanks
The TVFA breather valve with flame arrestor is a device that combines a Pressure Vacuum Relief Valve and a Flame Arrestor, installed on the top of storage tanks to protect them from overpressure, vacuum, and to prevent the risk of fire spreading back into the tank.
With its End of Line – Weight Loaded design, the valve helps maintain stable pressure inside the tank, reduces product vapor losses, and prevents air and flammable vapors from escaping into the environment, ensuring safety and environmental compliance.
✅ TVFA – The perfect choice for storage systems containing petroleum, chemicals, and volatile solvents, delivering high operational efficiency and absolute reliability.
