Abstract
A single actuator multi-port flow control valve composed of a plurality of generally cylindrically shaped port bodies rotatably mounted within a valve body. The port bodies are serially driven by a single actuator via a drive link system composed of a drive pin on the inferior side wall of a serial superior port body selectively abutting, during rotation, a driven tab on the superior side wall of its serially inferior port body. The position of each port body is known to an electronic controller which selectively actuates the actuator to set each port body angular position.
