The present invention is a valve for use in a central tire inflation system including a casing securable to the rim of a vehicle in communication with the tire that houses a main body connectable to a pressurized fluid supply of the central tire inflation system, and a valve member moveable within the main body to control the flow of air through the valve. The valve can be mounted flush on the exterior surface of the rim or in a recessed position within the rim, and can be connected to a manifold that is able to control the flow of pressurized fluid from the central tire inflation system to each valve and tire connected to the valve. The operation of the manifold and pressurized fluid supply can be controlled utilizing a controller operably connected to the manifold and fluid supply, and to sensing devices in the valve that supply information regarding the operational conditions of the vehicle to the controller to assist in adjusting the inflation of the tires as necessary.
