A locking device for quarter turn valves avoids the inadvertent, unauthorized or careless manipulation of quarter turn valves from a desired position thereby minimizing, if not eliminating, the likelihood for damage or injury in an industrial or other setting as a result of the unauthorized opening/closing of the valve. The locking device includes a shroud which is adapted to be placed over the upper end of the stem and adjacent portion of the handle on the valve. The shroud has a capping portion which securely engages a mounting pad of the valve and an upwardly extending channel designed to at least partially surround a portion of the handle. A hole is provided in the channel and aligns with a hole in an adjacent portion of the handle when the shroud is placed on the valve. As such, the post of a lock is easily inserted through the aligned holes. The locking device according to this invention advantageously prevents the unauthorized manipulation of the handle and the resulting rotation of the valve member to/from the open/closed positions.
