Abstract
A locking structure for a valve of the type where the valve member is turned less than 360 degrees between fully open and fully closed positions as, for example, a ball valve. This structure employs a stop pin on the valve body positioned to be engaged by the handle of the valve in the fully open and closed positions of the valve. A lock plate structure is journaled on the valve stem and is arranged to engage the opposite side of the stop pin from the handle in the fully open and fully closed positions of the valve, such that when a lock is secured in mating apertures in the lock plate and the handle, the valve will be securely locked in either a fully open or fully closed position.
