The air relief valve is used to allow air to escape during the system start up and also to allow air back into the drip line when the water is turned off.

The air relief valve helps prevent clogging in sub-surface drip irrigation systems due to suction of debris under vacuum conditions. The air relief valve should be installed at the highest point of a drip line layout.

    1" Kinetic Air Vent & Vacuum Relief Valve

    Regular Price:

    $12.00

    The 1” with MNPT kinetic air relief valve allows large volumes of air to escape from the irrigation pipe as the system is being filled when it is turned on. It also allows air into the pipe when the system is turned off. As the pipeline fills, water enters the air relief valve and raises the float to shut the valve. When the irrigation system turns off, the float drops, allowing air to enter the pipe and preventing possible vacuum in the pipe, pipeline collapse, and valve and drip emitter breakage. Air Vacuum Relief Valves offer an efficient means to fill and drain pipelines, providing full protection to the irrigation system components.
