Tank Venting & Equipment
P/V Vent With Flame Arrestor
The Defender Series® P/V Vent with Flame Arrestor regulates pressure and vacuum in underground storage tanks (UST), ensuring fuel vapors escape and outside air enters only within safe limits. Equipped with an internal rolling diaphragm, this vent provides stable and controlled opening performance, both under low and high pressure conditions, maintaining a low-leakage and efficient system. It is constructed using high-quality UV-resistant materials for long-term durability in various weather conditions. Furthermore, an integrated flame arrestor serves as an additional safety measure, preventing fire from spreading back to the tank, providing extra fire protection. The design also features an in-line vault, which provides additional protection and simplifies servicing and testing directly at ground level, without the need for heavy equipment or working at heights, making it a safe, efficient, and reliable solution.
