Air Release Valve

Removes entrained air from pressurized water systems to minimize water hammer

Air release valves automatically exhaust small amounts of air that collect in system high points once the system is filled and under pressure.

Air bubbles enter the top of the chamber and eventually displace liquid within the valve and lower its level to where the float is no longer buoyant. The float drops, which opens the valve seat and allows accumulated air to be exhausted to atmosphere. The liquid level then rises, raises the float, which, in turn, closes the valve seat.

Valves listed below have cast iron bodies with stainless steel internals and are rated 150 psi working pressure. Valve sizes through 1" have 3/32" orifices with 1/4" FNPT outlets and the 2" has a 3/16" orifice with a 1/2" FNPT outlet port.

Other sizes are available through 6" and 300 psi working pressure.
