Air Release (Venting) Valves – AR Series
The Chemline AR Series Air Release 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, 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 drops to the outlet pressure of the valve (normally atmospheric).

Features & Benefits
- Full Size Range
1/2” to 4” (4” valve is fabricated from a 3” valve). - Large Flow Capacities
Valves have full port liquid capacities, so for air flow they may be chosen several sizes smaller than the liquid pipeline. - Outlet Cap Available
For non-hazardous fluids, the optional removeable PE outlet cap prevents tampering with the union nut. Eliminates possible splashing during quick closure and covers the open end.
For hazardous fluids, a 3 foot pipe should be installed on the outlet side or the outlet should be piped to a containment area.
