PROBLEM TO BE SOLVED: To provide a selector valve that has a plurality of ports at a valve seat member and is configured to conduct by sliding a valve body by a plunger and thus changing the ports by the valve body, and that is tightly fixed to another device.SOLUTION: A selector valve (10) is constituted as a pilot valve of a four-way selector valve (20). A valve body 3 opposed to a valve seat member 2 is driven to allow a high-pressure fluid from a D port 21 to flow to a C selector port 22 or E selector port 23. The valve seat member 2 is constituted by forming a main body part 2A, a valve seat part 2B having a little smaller diameter than the main body part 2A, and a bracket 2C in one body. The selector valve (10) is fitted to a valve housing (20a) of the four-way selector valve (20) through the bracket 2C. The bracket 2C and the valve housing (20a) are fixed by welding or brazing.SELECTED DRAWING: Figure 2 |
