Stem
The stem connects the actuator and disk. It moves and positions the valve disk. The valve stem transports the required motion to the disc, plug, or the ball for opening, closing or positioning the valve. The stem connects actuator, handwheel or the lever of the valve at one end and the disc on the other end. In gate and globe valves, linear motion of the disc open or close the valve, while in the plug, ball, and butterfly valves, the disc rotates to open or shut the valve. Stems are typically forged from stainless steel and connected to the disk by threaded or welded joints.
