ABSTRACT:
A multiport valve for a water transfer system passes water, drawn by a pump, through a plurality of collectors. A programmable controller controls operation of the pump and a stepper motor which positions the multiport valve in a time series sequence according to user instructions. The multiport valve is formed with a first valve head having an intake port and multiple separate outlet ports. The respective outlet ports are connected to the respective collectors at respective collector inlets. A first rotor bears against the first valve head and forms a seal between the first rotor and first valve head. The first rotor is formed with a first coupling channel for coupling the intake port of the first valve head to different outlet ports according to the rotational position of the first rotor. The multiport valve incorporates a second valve head formed with an exhaust port and a plurality of separate inlet ports coupled to the respective plurality of collectors at respective collector outlets. A second rotor bears against the second valve head substantially forming a seal between the second rotor and second valve head. The second rotor is formed with a second coupling channel for coupling the exhaust port to different inlet ports according to the rotational position of the second rotor for exhausting water.
