OPW Utility Tank Vents

OPW Utility Tank Vents are installed directly on the top of aboveground storage tank or utility tank vent pipes. The vent cap is designed to protect the tank against
intrusion of water, debris or insects. The 515ML incorporates a flame arrestor screen for jurisdictions that require these on tanks. A normally closed poppet in the
valve opens at a predetermined pressure or vacuum setting to allow the tank to vent.
