Abstract
A control valve for irrigation and other purposes comprising an actuator mounted for rotation along a path, a motor for moving the actuator along the path, and first and second pilot valves located at first and second stations, respectively, along the path. As the actuator moves along the path, it sequentially engages the pilot valves and holds them in a first position. An adjustable selector is provided at each of the stations for controlling the length of time that the actuator holds the associated pilot valve in the first position to thereby control each of the pilot valves. The pilot valves are used to control main valves.
