Tank Venting & Equipment
P/V Vent With In-Line Vault
The Defender Series® P/V Vent with In-Line Vault regulates pressure and vacuum in underground storage tanks (UST). This component ensures vapor pressure is maintained at a certain level and outside air is allowed in, maintaining system stability and preventing fuel vapor leaks. Equipped with an internal rolling diaphragm, this vent provides precise opening response under both high and low pressure conditions, supporting low-leak performance and high-pressure control. Made of high-quality UV-resistant materials, this P/V Vent has a long service life, even in extreme environments. The in-line vault design provides additional protection while simplifying ground-level service and testing, eliminating the need for lifting equipment or working at heights, resulting in greater efficiency and safety.
