A valve body is provided with an annular groove that is recessed and communicates with the load path, and the ridges that intersect with the sliding holes on both sides of the annular groove are formed into valve seats of the same diameter. The valve part has a larger diameter than the seat and is formed in an annular hollow shape. One side of the valve part is provided with an annular switching groove that communicates with the inlet passage, and the other side is provided with an annular switching groove that communicates with the discharge passage so that the valve part can slide into the sliding hole. It is equipped with a valve body with sliding parts on both ends that can be fitted freely, and the valve part is formed in a shape whose diameter gradually increases from both switching grooves toward the annular groove side, and the load path is connected to the introduction path by the axial movement of the valve body. A directional control valve provided for switching communication between the and the discharge passage.
