OPW 723V-3203 3 in. Female NPT Pressure Vacuum Vent – 6,450 SCFH
Pressure Vacuum Vents are installed on the top of vent pipes from underground or aboveground fuel storage tanks. The vent cap and internal wire screen are designed to protect the tank vent lines against intrusion and blockage from 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.
SCFH = Standard Cubic Feet Per Hour at 2 psi pressure drop
