Abstract (en)
Provided is a flow channel switching valve that can ensure an excellent sealing property, operability, and stability, and can effectively prevent valve leakage. As seen in the horizontal direction (i.e., direction perpendicular to axis), the outer shape of the pressure receiving face (i.e., pressure receiving area Sc) of a first slide valve element (i.e., high-pressure side slide valve element) 15A adjacent to a second slide valve element (i.e., low-pressure side slide valve element) 15B (i.e., on the back pressure side) is set larger than the outer shape of an annular seal face 15s (or contact area Sb thereof) of the first slide valve element 15A.
