Abstract
A valve lock assembly comprising a post member and a slide member, in which the post member is affixed to the valve stem of a valve and the side member can slide up and down around the post member, the slide member being so configured that it engages one or more of the stops on the valve to prevent rotation of the valve handle between the stops but, when slid upwardly, disengages from the stop and permits rotation of the valve handle.
