Kinetic Air Release Valve

Kinetic Air Release Valve that combines both large orifice & small orifice functions within one unit. The large orifice allows air to be expelled from the system during filling of a pipeline and admit air back into the system whenever sub-atmospheric pressure occurs. Air is vented from the system until water enters the valve and lifts the float against its seat, ensuring a tight seal. In the event of sub-atmospheric pressure in the system, the water level drops causing the float to fall from its seat and allow the admission of air.

To release air when the main is being filled and to close and remain closed when the pipe is full to prevent loss of water. To open and admit air while the main is being emptied. To release air accumulated under pressure during normal working conditions in the pipe, again without loss of water. In Kinetic Air Valve, this operation is effected automatically by means of a ball float working in conjunction with an orifice of appropriate type for the duty
