Abstract
A valve cover apparatus is provided having a housing, lock and hook. The housing includes a top wall, bottom wall and a plurality of sidewalls. The bottom wall includes an opening to a central chamber of the housing which is sized for receipt of a valve handle and valve stem of a pipe valve. Preferably, the sidewalls include one or more inlets for receipt of the pipe's conduit. The lock is affixed and integrated into the top wall of the housing and constructed to lockably engage and disengage the hook. The hooks includes a vertically extending shaft and one or more shanks. The shanks extend horizontally under a pipe valve to inhibit upward movement of the hook once the hook has been positioned in place.
