Abstract
A lever-operated rotary valve having a rotary body for permitting fluid flow therein includes a locking device for selectively locking and unlocking the operating handle such that the operating handle of the rotary valve can be locked in a plurality of predetermined positions. The operating handle of the rotary valve can be oriented in any one of a plurality of positions and locked in that position without requiring the removal of the locking device. The locking device is an L-shaped member which fits on the stem of the rotary valve and includes aligned holes for receiving a padlock so that the locking device and handle are locked together.
