Abstract
An irrigation control system includes a rotary water motor which receives water from a valve, which has either a full on or a full off condition, depending on the alignment of an associated irrigation line. A pilot valve which is not susceptible to being clogged by contaminants that can be found in the water actuates the valve to the on or off position for controlling the water motor.
