An automatic flow control actuator having a weather resistant housing affixed to a transmission pipe or tubing to selectively control the flow of a fluid or gas to a discharge orifice via a valving mechanism connected to a control unit that controls the flow control actuator to move the valving mechanism variably between an open flow position and a closed no flow position. In one embodiment an automatic gated-pipe actuator is disclosed having a base plate affixed to an irrigation pipe, a weather resistant automatic gated pipe gate control unit case affixed to the base plate, a automatic gated pipe gate control unit disposed within the case, an irrigation valve and a mechanical actuator operably coupled to the gate control unit and to the irrigation valve wherein the mechanical actuator will actuate and alter the disposition of the irrigation valve to an open or closed position. The gated-pipe actuator may also utilize a memory for storing program instructions, a timer module, a power storage unit, a power charging unit, a manual override, a communications port, and a motor whereby the microprocessor controller instructs the motor to actuate in response to a set of instructions. The automatic gated-pipe actuator may control more than one irrigation valve and may have more than one motor to drive the mechanical actuators. The automatic gated-pipe actuator may receive commands from a control or moisture sensing unit. Thus, the automatic gated-pipe actuator acts to provide irrigation material to plants in a field based upon a set of instructions.
