ABSTRACT:
An improvement on a ball valve for use in detachably connecting a riser pipe to an irrigation lateral. The novel valve has a throat operatively connected to the outlet end of the valve. The throat receives a valve trigger tube which has spaced fingers extending longitudinally from the end of the pipe to engage the ball, thereby forming apertures between the fingers which serve as a strainer to prevent the passage of foreign objects and which can be sized to regulate the flow of water. When the tube is withdrawn the flow of the water through the then open end of the tube generates a self-cleaning action.
