    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： The present invention aims to provide a directional control valve excellent in the detecting accuracy and the operational stability and having a position detecting function, wherein the magnet is prevented from directly contacting hydraulic fluid so as not to be affected by the hydraulic fluid. To achieve this, a magnet 21 is installed on an end portion of the valve member 6 received in the valve hole 5 so as to be situated at a position which is adjacent to a breathing chamber 9 and which is more exterior than an end sealing member 8 which shuts off the breathing chambers from the hydraulic fluid passages, and also a magnetic sensor 22 is installed at a position opposite to the magnet 21, in a casing 4, whereby the magnetic sensor 22 detects the magnetic flux density when the magnet 21 moves together with a spool 6, and detects all operating positions of the spool 6 during a stroke, from the change in the magnetic flux density.
