A device,usually referred to as a P/V vent, installed at the discharge end of a vent pipe connected to a gasoline storage tank,to regulate the pressure at which vapor is allowed to escape from the tank,and the vacuum at which outside air is allowed to enter the tank.A gasoline storage tank needs to breathe. If vapor that builds up inside the tank couldn't get out,itPressure Vacuum Vents OPW Retail FuelingOPW 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.Pressure and Vacuum Relief Vents ProtectosealPressure / Vacuum Relief Vents are employed where it is necessary or desirable to reduce evaporation of tank contents to atmosphere.These vents are generally designated as the conservation type.They are typically mounted to a flange or pipe that connects to the vapor space (space within the tank that is above the liquid surface) of a storage
