磁方向切換弁。An annular groove communicating with the load side is provided by recessing the inner circumference near the introduction passage opening of a circular housing hole in which an introduction passage for introducing pressure fluid is opened on the inner circumference. A valve body has a valve seat formed on a ridge that intersects with the inner peripheral surface of the housing hole, and an annular switching groove is recessed and communicated with the introduction path on the outer peripheral surface that is slidably inserted into the housing hole. , a valve body provided with a switching part in the shape of an annular protrusion with a diameter larger than the hole diameter of the valve seat part so as to be connected to the switching groove and positioned in the annular groove, and the valve element is actuated to two positions in the axial direction. The valve body is equipped with an electromagnetic device and a return spring arranged to act in opposition to each other, and the valve body has a seated side that is seated on the valve seat of the switching section conically shaped into an annular groove to make line contact or close contact. An electromagnetic directional control valve is provided with a communication passage passing through the interior to the low pressure side so as to equalize the pressure on both end faces, and to apply the acting force of an electromagnetic device to the valve body via a spring.
