A valve seat is disposed within the fluid passageway. A movable valve plug is disposed within the fluid passageway, and the valve plug interacts with the valve seat to selectively open or close the fluid passageway. A cage is disposed in the fluid passageway, the cage surrounds the valve plug, and the cage includes a mechanical stop that limits movement of the valve plug within the cage away from the valve seat.
