<p>Inexpensive three-port solenoid valves that can be connected to five-port solenoid transfer valves and allow the axial movement of valve discs to be stably guided, are provided. Two valve discs 25A and 25B constituting a three-port valve are inserted into a five-port valve body 15 having a supply channel 21 opened at the center of a valve hole 20; output channels 22A and 22B opened on the respective sides of the supply channel; and ejection channels 23A and 23B opened on the respective sides of the output channels. A pilot-valve section 12 is used to drive the valve discs. The valve discs use the fluid pressure in the supply channel 21 as returning force for the valve bodies, and each have seal members 28A, 28B and 29A, 29B for switching the output channels 22A and 22B between the supply channel 21 and the ejection channels 23A and 23B, respectively, for communication; and guide sections 35 and 36 for guiding the axial movement of the valve discs, wherein a fluid groove 37 for a fluid flowing through the channel is provided between the plurality of axial guide sections 36. <IMAGE></p> |
