摘要
A process control valve includes a valve stem, a valve plug. The valve stem and the valve plug are attached to one another by an arrangement that includes a locking pin that passes through substantially aligned bores in the valve stem and the valve plug. The locking pin is positively retained mechanically and prevented from extending outside of the bores in the valve stem and the valve plug.
