1. An irrigation control device comprising:

  • a coil configured to develop an electromagnetic flux sufficient to cause actuation of irrigation equipment;

    control circuitry electrically coupled to the coil and configured to receive, at input connections, modulated power signals from an external irrigation control unit of an irrigation control system via a control wire path coupled to the input connections, wherein the control circuitry is configured to derive control signals from the modulated power signals received from the control wire path and based on the control signals, output signaling to the coil to control the electromagnetic flux at the coil; and

    a housing covering at least a portion of the coil and at least a portion of the control circuitry, the housing having;

    a wall portion including a flat mid-wall generally extending around a portion of the coil and a pair of curved walls extending from the flat mid-wall and generally extending around a portion of the coil and generally corresponding to a curvature of the portion of the coil;

    a radially expanded portion including a curved wall positioned opposite the flat mid-wall and generally extending around the control circuitry; and

    a pair of curved walls extending from a respective one of the curved walls that extend from the flat mid-wall and connect the curved walls that extend from the flat mid-wall to the curved wall of the radially expanded portion, the curved walls that extend from the curve walls extending from the flat mid-wall generally extending around a portion of the coil and generally extending around a portion of the circuitry.
