An adsorbent fractionator directional flow control valve assembly includes two inlet check poppet valves, two outlet check poppet valves, and a valve body. The valve assembly controls the directional flow of an influent gas mixture into one of two vertical desiccant tanks of an adsorbent fractionator, or desiccant dryer, and an effluent gas flowing in reverse through the opposite desiccant tank. The valve body is a single unitary piece, which may be a casting, and couples the inlet check poppet valves and the outlet check poppet valves, which may be four identical valve subassemblies, providing flow communication between these and an inlet port, two exit ports, and an outlet port.
