ABSTRACT:
Self-contained, automated flow control system for use in a water distribution system such as a sprinkler system. The system has a master valve which controls communication between a supply line and a manifold, and a plurality of control valves which control communication between the manifold and a plurality of outlet lines. An anti-siphon valve is connected between the master valve and the control valves to prevent water from being drawn back into the supply line from the outlet lines. Operation of the master valve and control valves is controlled by a clock timer which is programmed to actuate the valves in a predetermined sequence and to open the master valve only when one of the control valves is open.
