Abstract: A valve for use in distributing irrigation water in a surge irrigation system. The valve having a diverter member rotatably mounted within the cylindrical cavity of a valve body. The diverter member has an arcuate diverter plate mounted thereon which conforms to the curvature of the cylindrical cavity and wiper blades extending from said diverter plate into the space between said plate and the interior of the valve body. Upon circulatory or oscillatory rotation of the diverter member, the wiper blades sweep the interior of the valve body. The diverter plate may be selectively aligned with one of the outlet ports in the valve body, thereby diverting flow from the inlet port to the remaining outlet ports. The diverter member design minimizes engagement with particulate matter and it minimizes the force exerted upon this member by the irrigation water to decrease the torque and corresponding power consumption required to rotate the diverter member.
