Automatic low pressure pipeline valves and the associated controls for surface irrigation are described. Design information for 6-in., 8-in., and 10-in. (150-mm, 200-mm, and 250-mm) valves is presented. The valves, which use battery-powered control units and operate on water from the pipeline, can be used independently without an outside source of energy. Small 3-way pilot or selector valves are used to control opening and closing of the irrigation valves. The pilot valve is operated by a 3-V DC battery-powered motor. The motor/pilot-valve unit is versatile and can be used with mechanical and electronic timers, commercial irrigation controllers, or radio transmitter/receiver units. The automatic valves, with an experimental electronic timer, were field tested using gated pipe to irrigate corn with automatically cutback furrow streams. They were also used with a commercial irrigation controller to irrigate beans with short frequent irrigations.
