A lockable sprayer shutoff valve has a housing and an upstream hose insert which is slip-fit into the upstream end of a slidably mounted valve sleeve. An O-ring seal is provided between the hose insert and the valve sleeve. The downstream end of the valve sleeve is slip-fit with an O-ring seal over the upstream end of a tubular wand sleeve supported in the downstream end of the housing. A valve plug is generally centered in the valve sleeve for sealing contact with the downstream end of the hose insert when the valve sleeve is in a closed position. When the valve is in the open position fluid is allowed to flow through the hose insert, around the valve plug through slot openings which circumscribe the plug, through the valve sleeve and through the wand sleeve. At least one locking finger is provided on the valve housing. The locking finger can be positioned to interfere with the sliding movement of the valve sleeve and thereby lock the valve sleeve in either the open or closed position.

A valve for controlling the flow of a liquid comprising: a tubular housing; a tubular upstream input member supported in said housing and defining an inlet passage therethrough; a tubular downstream outlet member supported in said housing defining an outlet passage therethrough and being spaced from said input member to create a space between said input and outlet members; a valve sleeve slidably mounted on said input and outlet member; a valve plug supported in said valve sleeve, said valve plug being aligned with said input member for closing said passage through said input member when positioned adjacent said input member; said valve sleeve being slidable between a first position with said plug adjacent said input member, closing said input passage, and a second position in which said plug is spaced from both said input member and said outlet member, said sleeve encompassing said input and outlet members in both said first and second positions to define a fluid flow passage between said input and outlet passage in both said first and second positions and at all positions therebetween; there being an opening between said valve plug and the interior surface of said valve sleeve whereby when said valve plug is in a position spaced from said input member and said outlet member, fluid can flow from said inlet passage, through said valve sleeve, past said valve plug and out of said valve sleeve through said outlet passage.
