Summary:A shuttle valve for a gas drying system that cleans and drys a stream of unpurified pressurized gas received from a source thereof and supplied to a pneumatic system that uses such a purified pressurized air. The valve includes a housing that connects a drying assembly to a structure that conveys the unpurified pressurized air to the drying assembly. The housing contains a choke disc provided with an office and a movable piston located in axial alignment with the choke disc. When the unpurified pressurized air is directed into the drying assembly for drying, the piston moves away from the choke disc to permit dry air to freely flow from the drying assembly and through the valve to the system utilizing purified pressurized air.
