1. An irrigation control device comprising:
- a coil configured to develop an electromagnetic flux sufficient to cause actuation of irrigation equipment;
control circuitry coupled to the coil and configured to receive, at input connections, control signals comprising a modulated power signal from an external irrigation control unit of an irrigation control system and configured to control the electromagnetic flux at the coil based on the control signals, wherein the control circuitry is configured to derive data from the modulated power signal and based on the data, output signaling to the coil to cause the coil to develop the flux; 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 and a pair of curved walls extending from the flat mid-wall and generally corresponding to a curvature of the coil; and
a radially expanded portion including a curved wall positioned opposite the flat mid-wall, the curved walls extending from the flat mid-wall being connected to the curved outer wall by a pair of curved walls extending from a respective one of the curved walls that extend from the flat mid-wall;
a threaded end configured to thread the irrigation control device to a valve assembly to be actuated by the electromagnetic flux of the coil, the threaded end including an aperture;
a curable, electrically non-conductive potting material substantially holding the control circuitry in a fixed position relative to the coil within the housing;
a core tube within the housing and at least in part extending between the coil, the core tube being separated from the control circuitry at least by the potting material; and
a valve member within the housing and located relative to the coil, the core tube, and the aperture such that the valve member is configured to move within the core tube and through the aperture of the threaded end to cause engagement with a valve seat external to the housing in response to the electromagnetic flux;
wherein the control circuitry is further configured to communicate to the external irrigation control unit via the input connections.

Abstract
An irrigation control device comprises a coil adapted to develop an electromagnetic flux sufficient to cause actuation of irrigation equipment. Control circuitry is electrically coupled to the coil to receive control signals from an irrigation control unit and to control the flux at the coil. A housing covers at least a portion of both the coil and the control circuitry, the housing including a threaded end configured to thread the irrigation control device to a valve assembly to be actuated by the electromagnetic flux of the coil.
