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.
