摘要： A gate valve having a flow passage therethrough is provided with a valve stem movable disc having an opening permitting fluid flow through the passageway when in register therewith and interrupting fluid flow when the disc is in a valve closed position. The disc is provided with a removable cylindrical plug mating with ring-like seats on opposite sides of the disc surrounding and coaxial with the flow passageway. Ratchet teeth on the plug engage a detent to rotate it through a predetermined arc each time the gate valve is closed.
