Abstract
A valve is provided that comprises a valve chamber including first and second valve port openings in communication with first and second inlet/outlets, respectively. A shaft is rotatably disposed in the valve chamber. A first valve plate is rotatably coupled to the shaft that is disposed in the valve chamber over the first valve port opening. The first valve plate has a first opening positioned so as to align with the first valve port opening. The first valve plate is configured to rotate from its closed position covering the first valve port opening to an open position, where rotation of the first valve plate adjustably positions at least a portion of the first opening over the first valve port opening. A second valve plate is configured to rotate with the first valve plate, and to cover the second valve port opening.
