摘要： A pipe joint is provided wherein quick joints assembly are installable in two ports and in a fluid pressure apparatus such as a solenoid transfer valve as in the prior art, while joints with a female thread are interchangeable with the guide joints so as not to rotate even when male screw members for piping are screwed in. The quick joints and the joints with a female thread are interchangeably installed in a fluid pressure apparatus in which two ports are switched and supplied with a pressurized fluid. Although the quick joints and the joints with a female thread can be installed as in the prior art, the joints with a female thread are integrally connected and fixed between the quick joints and the joints with a female thread via a connection member so as not to rotate even when male screw members for piping are screwed in.

摘要： Inexpensive two-port solenoid valves that can be connected with five-port solenoid transfer valves are provided. Two valve discs 25A and 25B constituting a two-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 are opened on the respective sides of the supply channel; and ejection channels 23A and 23B are opened on the respective sides of the output channels. A pilot valve section 12 is used to drive the valve discs. The valve discs 25A and 25B use the fluid pressure in the supply channel 21 as returning force for the valve bodies, and each has seal members 28A and 28B for continuously sealing the portion between the output channels 22A and 22B and the ejection channels 23A and 23B, respectively, regardless of the operating positions of the valve discs; and each also has seal members 29A and 29B for opening and closing the portion between the supply channel 21 and the output channels 22A and 22B, respectively.

摘要： In a pilot selector valve, a first output opening 25A in a valve hole 24 is opened relative to a first output channel 32b formed on the top surface of the valve body 18 using a first enlarged channel 32a with its width which is orthogonal to the connecting surface of the valve body is made larger than its width in the axial direction. The first output channel is formed by attaching a top cover 21 to the valve body 21. A second output opening 25B located opposite the first output channel is opened relative to the bottom surface of the valve body 18 using a second enlarged channel 33a similar to the first enlarged channel. A through hole 33c for allowing the second enlarged channel 33a to communicate with a second output port B is opened in the valve body with the opening end of the second enlarged channel 33a closed with a bottom.
