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.

Integrated control circuitry and coil assembly for irrigation control

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.

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 spacer is configured to maintain the coil at a predetermined position relative to the control circuitry.

Integrated irrigation valve control device for a multi-wire irrigation control system

An improved gear drive sprinkler has a pop-up spray head adapted for adjustable part-circle or full circle operation to deliver irrigation water over a selected terrain area. The sprinkler includes a pop-up riser; a gear drive transmission mounted within the riser includes a water-driven turbine for rotatably driving a speed reduction gear train, which in turn rotatably drives the spray head. A reverse assembly includes an upper trip unit defining an individually adjustable pair of end trip stops, and a lower shift mechanism including a shiftable director plate having first and second sets of angularly oriented jet nozzles for respective alignment with turbine jet ports for respectively driving the water-driven turbine and the gear train in a forward-drive or a reverse-drive direction. The upper trip is coupled to the director plate by an elongated trip rod which shifts the director plate between forward-drive and reverse drive positions. An adjustment cam can be manipulated to disable at least one of the end trip stops to permit spray head rotation through continuous full circle revolutions.
