Utility Tank Vent

OPW Utility Tank Vents are installed directly on the top of aboveground storage tanks or utility tank vent pipes. The vent cap is designed to protect the tank against intrusion of water, debris or insects. A normally closed poppet in the valve opens at a predetermined pressure or vacuum setting to allow the tank to vent.
