Abstract
A lock apparatus for a valve that has a valve body and an actuator stem protruding therefrom for selectively rotating a flow control member within the valve body between open and closed positions and a handle attached to the valve stem that defines a first axis. The lock apparatus includes a slider plate that is movably supported on the valve stem and is selectively slidable along a second axis that is substantially transverse to the first axis to a position wherein said slider plate contacts a portion of the valve body when the flow control member is in either of the open and closed positions to retain the flow control member therein and another position wherein the slider plate does not contact the portion of the valve body to permit the valve stem to be rotated. An opening is provided through the slider plate for receiving a portion of a locking device therethrough.
