Abstract
An air relief valve for use with an irrigation pipe. The valve comprises a base attached to the wall of the pipe, a vent extending from the interior of the pipe to the exterior of the pipe, a shutoff mechanism, and a water level sensor disposed within the pipe. The vent has an inlet adapted to face the interior of the pipe and an outlet adapted to face the exterior of the pipe. The shutoff mechanism is pivotally articulated to the base between an opening position thereof wherein air can exit the pipe via the vent and a closing position thereof wherein air is prevented from exiting the pipe via the vent. The shutoff mechanism is responsive to the water level sensor to selectively pivot between the opening and the closing positions.
