The drive sleeve is coupled to the stem and isolates the moveable connection between the sleeve and the stem from fluid in the valve. The drive sleeve is also coupled to the gate such that movement of the drive sleeve along the 67 stem moves the gate between the open and closed positions of the valve.Systems and methods incorporating the non-rising stem gate valve are alsodisclosed.
