1. A rotary control valve arrangement for a liquid conditioning system including:

  • a housing having a side wall forming a chamber and a plurality of ports formed in said side wall;

    a rotor having a first end, a second end and a longitudinal central axis, said rotor adapted to be located within said chamber of said housing and to be selectively rotatable about said central axis, said rotor including a generally tubular wall extending along said central axis, said tubular wall defining a longitudinally extending central fluid path, said rotor including an inlet port adapted to provide fluid communication between said central fluid path and a source of untreated liquid, said rotor including a plurality of longitudinal sectors, a plurality of said sectors including a plurality of radial chambers, one or more of said radial chambers including an aperture providing fluid communication between said central fluid path and said one or more of said radial chambers, each said radial chamber including a peripheral aperture adapted to selectively place said radial chamber in fluid communication with one or more of said ports in said housing and at least one of said radial chambers including a peripheral aperture adapted to selectively place said at least one radial chamber in fluid communication with more than one of said ports in said housing;

    wherein said rotor is selectively rotatable about said central axis to a selected one of a plurality of rotational positions such that said radial chambers of one of said sectors are aligned in juxtaposition and in fluid communication with said ports of said housing, whereby various fluid paths extending through said rotor and said ports are opened and closed as said rotor is selectively rotated between said rotational positions.
