A motorized valve including: a valve body having a housing wall and one or more inlet ports and a plurality of outlet ports penetrating the housing wall; each outlet port being arranged in spaced relationship from one another about a seat face, said seat face substantially conforming to an inner face of circular cylinder and each said outlet port having an orifice penetrating said seat face; a valve stopper having a stopper body formed with a sealing face conforming to an outer face of a circular cylinder commensurate with the dimensions of said seat face whereby said stopper body is rotatable within the valve body about a common axis shared by the valve body and the valve stopper, a valve stem extending axially from the stopper body, and a fluid communication passage formed into said stopper body for providing fluid communication between said one or more inlet ports penetrating said housing wall and a selected one or more of said outlet ports; and drive means operatively interposed between said valve stem and said valve housing for generating relative rotating motion of said valve stopper with respect to said valve body. |
