A device for distributing compressed air from a compressed air source to a plurality of apparatus that use compressed air. The device comprises a housing having valve chambers, inlet ports for connecting the valve chambers to the compressed air source, outlet ports, and exhaust ports communicating with outside the device. Each outlet port is adapted to communicate with at least one of the apparatus that use compressed air. Spherical valve bodies movably are provided in the valve chambers, respectively, each for closing one inlet port and one exhaust port. Shafts extend from the valve bodies, respectively. Each shaft has an end portion passing through one exhaust port and protruding from the housing. Electromagnetic actuators are coupled to the end portions of the shafts, respectively. Each actuator moves one valve body between an air-supplying position where the valve body closes the exhaust port and connecting the inlet port and the outlet port and an air-exhausting position where the valve body closes inlet port and connecting the outlet port and the exhaust port.
