ABSTRACT:
A fluid valve having a housing with an inlet and outlet. A valve closure is carried between the inlet and outlet by a stem journaled within the housing. A handle which is rotative relative to the stem and which is utilized to rotate the valve closure is provided. A lock member is carried by the valve housing and is contacted by the handle which, upon rotation, causes the lock member to rotate with the handle relative to the valve housing. A connector extends between the valve stem and the lock member so that, upon movement of the lock member, the connector causes the valve stem to rotate, thus rotating the valve closure within the valve housing.
