    Air Compressor Air Flow Check Valves

    Prevent air from escaping an air storage tank when the air compressor is not running. These valves install on the inlet of a tank. They open to allow airflow into the tank and close when flow stops or reverses direction. They have a 1/8 NPT tapped unloader port with removable plug for connecting to a pressure switch.
