シール部材を収装して成る方向切換弁。 A pressure channel that is open and communicates with the inner peripheral surface of the fitting hole provided in the valve body to supply pressure liquid, a load channel that connects to the actuator side, and a discharge channel that connects to the low pressure side in the axial direction of the fitting hole. A cylindrical sleeve is liquid-tightly fitted into the fitting hole, and a communication hole is formed through the sleeve to open and communicate each flow path on the inner peripheral surface, so that the flow direction of the liquid is adjusted. The spool is slidably fitted, and the spool has an annular groove formed in the land between it and the inner peripheral surface of the sleeve. It houses a metal seal member whose diameter is expandable by cutting a part of the annular shape so that it comes into pressure contact with the inner circumferential surface of the sleeve and one side of the annular groove by the acting force of the pressure liquid in the flow path to be switched and controlled. Directional valve.
