Abstract
To provide a decompression switching valve that enables reduction in the running cost and initial cost, by saving of air consumption and simplifying and downsizing of equipment. A decompression switching valve includes one valve hole, a main valve body having air supply ports, a first output port, a second output port, and an air exhaust port which are communicated with the valve hole, and a first spool and a second spool which are slidably provided in the valve hole, adjacent to each other, wherein the first spool forms a switching valve section that selectively connects the first output port to an air supply port or the air exhaust port, and wherein the second spool forms a decompression valve section that reduces the pressure of compressed air having been input from the air supply port and outputs the pressure from the second output port.
