Abstract

An automatic gated-pipe actuator for controlling flow of an irrigation material to an agricultural region through an irrigation gate in a gated-irrigation pipe. The automatic gated-pipe actuator includes a gate valve for coupling to the gated-irrigation pipe, a gate actuator removably coupled to the gate valve and for actuating the gate valve and an automatic gated pipe gate control unit for controlling actuation of the gate valve. The control unit has a processor unit communicatively coupled to the gate actuator. Upon instruction from the gate control unit, the gate actuator will actuate and alter the disposition of the gate valve thereby altering the flow of irrigation material through the irrigation gate and to a portion of the agricultural region adjacent the irrigation gate.
