ABSTRACT:
A control valve is provided for a water conditioning system having a mineral tank. The control valve includes a housing having an upper body portion and a lower body portion. The housing defines a chamber located between the upper and lower body portions. The upper body portion includes a first upper port, a second upper port, and a third upper port. The lower body portion includes a first lower port, second lower port, and a third lower port which provide fluid communication with the tank. A cylindrical disk is located within the chamber and is selectively rotatable about a central axis. The disk includes an upper face having a generally centrally located aperture and a peripherally located aperture. The disk also includes a spaced apart lower face having a first peripherally located aperture and a second peripherally located aperture. A first fluid passage extends through the disk between the centrally located aperture in the upper face and the first peripherally located aperture in the lower face. A second fluid passage extends through the disk between the peripherally located aperture in the upper face and the second peripherally located aperture in the lower face. Rotation of the disk about the central axis to one of various different positions as desired provides selective fluid communication between the upper ports in the upper body portion and the lower ports in the lower body portion of the control valve.
