    Abstract: A flow actuated automatic valve has first and second ends and a passageway formed therethrough having first, second and middle portions, a ball positioned in the middle portion of the passageway, means for preventing the ball from passing through the first end portion of the passageway, and a ball seating element positioned in the second end portion of the passageway. The ball seating element has an interrupted annular seating surface extending about an opening therethrough which is in communication with the middle and second end portions of the passageway. The seating surface is mateable with the ball for receiving the ball and reducing the flow of fluid to the valve in response to a preselected flow rate through said valve.
