ABSTRACT:
An in-line ball valve having a locking device which permits the positioning of the valve member to a set position by operation of a valve handle with the valve member being locked in this position against any creeping movement by reason of flow-induced forces acting on the valve member. The valve also includes a handle design which permits the handle to be positioned on the shaft of the valve member in eight different handle configurations to provide for simplicity of installation and ease of adaptability to push-pull controls.
