Abstract: A control unit for operating a valve system in a water conditioner system includes a drive motor having an output shaft coupled to the valve system, a valve position slide switch, an electronic regeneration controller, and a settable mechanical clock. The electronic controller can be programmed by the use of electrical jumpers/dip switches/control knobs. As the drive motor drives the output shaft coupled to the valve system, the drive motor also contemporaneously rotates a dual lead screw in the valve position slide switch. The dual lead screw drives an electrical contactor along a series of electrical contacts in a closed loop fashion. Each of the discrete electrical contacts corresponds to a position of the valve. The electronic controller controls the position of the valve in accordance with dwell times programmed into the electronic controller. If a demand regeneration scheme is desirable, a hardness setting rotary potentiometer can be used to provide analog electrical control.

Abstract: A water conditioner rotary valve for use in a water conditioning system includes a valve body constructed of an upper section, a lower section and a middle section, to facilitate ease in assembly of the body. The valve rotor member of the conditioner valve is driven by a Geneva drive system, to provide accurate positioning of the rotor member in its various positions. A valve seat member is located adjacent the rotor member, and provides a construction which improves the seal between the rotor member and the surface of the valve body adjacent thereto. The three-piece assembly of the valve body facilitates providing a valve capable of either upflow or downflow brining by replacing the lower valve section. A brine injector valve is mounted exteriorly of the valve body.
