Patent ID: 7219685

Claim:
A locking assembly for a gate valve having a hand wheel with a plurality of spaced spokes emanating from a central hub, a spacing between adjacent spokes and rotatable relative to a valve stem projecting through a truss having at least two spaced truss arms extending upwardly from a body of the gate valve, the locking assembly comprising: a bracket adapted to be mounted to one of the at least two truss arms; a mast extending upwardly from the bracket and adapted to project through the hand wheel between a pair of adjacent spokes when the bracket is mounted to one of the at least two truss arms; and a cap having at least two spaced spoke detents projecting downwardly therefrom; wherein the cap is adapted to be mounted atop the hand wheel coupling with the mast and the spoke detents each being inserted into respective spacings between the spokes of the hand wheel when the bracket is mounted to one of the at least two truss arms to thereby inhibit rotation of the hand wheel relative to the stem.
