PROBLEM TO BE SOLVED: To provide a four-way selector valve capable of switching flow passages by merely rotating a valve body, cutting out all flow passages, simplifying a structure, and being manufactured easily. SOLUTION: This four-way selector valve comprises a casing 11 and a valve body 12 peripherally and rotatably installed water-tight in the casing 11. 1st and 2nd inflow ports 13 and 14 are provided in the casing 11 at positions spaced in circumferential direction of the valve body 12, and 1st and 2nd outflow ports 15 and 16 are provided at positions spaced in circumferential direction of the valve body 12. The valve body 12 can be switched between a first rotating position for communicating the first inflow port 13 with the first outflow port 15 by the rotating angle of the valve body 12 and cutting out the second inflow port 14 from the second outflow port 16, a second rotating position for communicating the first inflow port 13 with the second outflow port 16 and cutting out the second inflow port 14 from the first outflow port 15, and a third rotating position for cutting out all inflow ports and outflow ports.
