ABSTRACT:
A valve handle latching assembly having a selectable latching slider which engages a detent on a fluid control device such as a ball valve. During assembly, a particular slider is selected for inclusion in the final assembly resulting in a valve tailored for its intended purpose. Depending upon which latching slider is selected, the valve handle latching assembly latches in the open and/or closed position(s) thereby preventing inadvertent rotation. The latching handle assembly may be manually disengaged to permit rotation of the handle in the opposite rotational direction.
