Defender Series® Pressure/Vacuum (P/V) vents regulate the pressure at which vapor is allowed to escape from the underground storage tank and the vacuum at which outside air is allowed to enter the tank. The P/V vent’s internal rolling diaphragm delivers consistent and controlled cracking for both low leak and high-pressure conditions while the superior construction of UV-resistant materials extends the overall service life. The in-line vault provides added protection and facilitates at-grade servicing and testing. This eliminates the added expense of lift trucks as well as the potential safety concerns of conducting work at height.
The HEALY™ 800 Series Onboard Refueling Vapor Recovery (ORVR) nozzle converts any new or existing dispenser to a CARB certified system for ORVR compatibility. The smart interface design will automatically detect whether a vehicle is equipped with ORVR to prevent over-pressurization caused by clean air being pulled back into the storage tank. Available for use outside of the United States.
