PROBLEM TO BE SOLVED: To select flow passages in multi-directions of necessary number and prevent mutual contamination between fluids in a single multi-way selector valve. SOLUTION: This multi-way selector valve is provided with a valve casing 1 including plural port 5a, 6a, 7a communicating to an internal cavity 1e, a valve spool 2 with irrotational section slidably arranged in the internal cavity le of the valve casing 1 and including plural fluid passages 3a, 4a, and packings 10, 11 arranged between inner walls 1a, 1b, 1c, 1d forming the internal cavity 1e of the valve casing 1 and the valve spool 2 and preventing leak of fluid from the ports 5a, 6a, 7a and fluid passages 3a, 4a. Consequently, connection between the ports 5a, 6a, 7a and plural fluid passages 3a, 4a can be selectively changed by sliding the valve spool along the inner walls 1a, 1b, 1c, 1d of the valve casing 1.
