Pressure vacuum vents are installed on the top of underground and low volume aboveground storage tank vent pipes. Vent allows tank to “breathe” during filling and discharging operations. Pressure and vacuum poppets seal vapors in tank when pressure is equalized. Settings are approximate.
WARNING: This vent must only be used in conjunction with motor fueling and/or low capacity flow. Fluid handling in lines larger than that used for retail service stations can cause tank to rupture or implode.
