  • System and method for restricting access to a valve
    Patent number: 8074960
    Abstract: A method and system for restricting access to a valve stem of a valve by employing a valve locking assembly is disclosed. The locking assembly comprises a first means for receiving a valve stem of a valve and an engaging member. The locking assembly additionally comprises a second means for receiving the valve stem of the valve and comprising a slide for engaging the engaging member of the first means, the slide having a first length along an outer periphery of the second means and a second length intersecting the first length such that the second length is shorter than the first length. The locking assembly additionally comprises a third means for releasably securing the second means in position about the valve stem of the valve, wherein the first means is capable of being positioned over the second and the third means about the valve stem.
