Abstract
An integrated irrigation valve control device has a coil adapted to develop an electromagnetic flux sufficient to cause actuation of irrigation equipment. Control circuitry is electrically coupled to the coil to control the flux at the coil. A housing covers at least a portion of the coil and at least a portion of the control circuitry.
Claims22
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.

A method of making an irrigation control device comprising:
- holding a solenoid assembly with a coil near to control circuitry for controlling an electromagnetic flux at the coil, the control circuitry having input connections adapted to be coupled to an external irrigation control unit of an irrigation control system via a control wire path to be coupled to the input connections;
- electrically connecting the coil to the control circuitry;
- placing the solenoid assembly and control circuitry into a housing;
- securing the solenoid assembly to the housing so that the solenoid assembly can be actuated to reciprocate a valve member through an aperture in the housing to selectively engage a valve seat;
- and
- fixing the control circuitry and coil within the housing;
- wherein the control circuitry is configured to receive, at the input connections, modulated power signals from the external irrigation control unit via the control wire path coupled to the input connections, and wherein the control circuitry is configured to derive control signals from the modulated power signals and based on the control signals, output signaling to the coil to control the electromagnetic flux at the coil.
