ABSTRACT:
An automatic water control valve for a lawn sprinkler system for maintaining soil moisture at a preset level. A spring loaded mechanism opens the valve when released by a water sensitive element which monitors the moisture content of the ground area serviced by the sprinkler system. A closing mechanism which is actuated by water flowing through the valve automatically resets the spring loaded opening mechanism and closes the valve after a fixed quantity of water flow.
