Abstract
A diverter valve includes a cup-shaped, substantially cylindrical body with a plurality of ports extending from the side of the body, each communicating with a hollow in the body. A disk shaped top is held in sealing engagement with the body. A plug is rotatably positioned within the body and seals against the body for closing a selected one of the plurality of ports. A portion of the plug extends through the top to permit the plug to be turned. A handle is coupled to the extending portion of the plug. The handle has an adjustable stop for limiting the rotation of the plug.
