The Chemline AR Series Air Release (venting) Valve allow gases to escape from unpressurized pipe lines. It must be installed vertically at the highest point in the piping system with the “Air” arrow up. As the unpressurized air vents, liquid rises to the float (an inverted cup), which lifts the float up against the seat, holding liquid pressure. The float will not
release until the pressure on the inlet side of the valve is equal to the outlet pressure of the valve (normally atmospheric).
