Abstract
A locking device for a control valve having a valve body and an operating handle rotatably shiftable between two positions, including a base member mountable on the valve for swinging movement co-axially with the handle and a locking member mounted on the base member for dependent swinging movement therewith and independent pivotal movement relative thereto and normal with respect to the swinging axis. The base and locking members each have opposed shoulders disposed for abutment with respective opposite sides of the handle and the locking member has a depending leg disposed to engage the valve body. Pivotal movement of the locking member permits selective swinging of the device. Upon abutment of the appropriate shoulders of the device against the side of the handle intermediate its two positions, the locking member is pivoted downwardly onto the base member to simultaneously engage the valve body with the depending leg, thereby to lock the handle against rotation.
