    Abstract: A control valve includes a valve housing, a plurality of valves located within the valve housing, and a moveable member that is configured to move within the housing, the moveable member including a plurality of cam extensions. As the moveable member moves (e.g., rotates), the cam extensions interact against the valves to open and close the valves in a prescribed order. The control valve may be controlled to inflate a zoned object. The valves may include at least two zone valves for communicating pressurized air into the object, and a vent valve for venting the object via the zone valves. At any given position of the moveable member, the cam extensions are positioned to one of: opening one of the zone valves, opening one of the zone valves and the vent valve, or maintaining all of the valves closed. The rotating member may be a cylindrical cam shaft with radially extending cams.
