PROBLEM TO BE SOLVED: To prevent the wear of the closing part and improve the durability of the valve body itself by constituting a multiple way valve in a way that a valve casing is provided having an upper chamber with a fluid inlet and a lower chamber with a fluid outlet and a desired communicated port is opened by moving either one of the plural valves equipped in the upper chamber. SOLUTION: A valve casing 18 is divided into an upper chamber 18e and a lower chamber 18f by a dividing wall 18d having three communicative ports 18a-18c. The upper chamber 18e is provided with a raw water inlet 15, and the lower chamber 18f is provided with a raw water feeding port 16 and a raw water outlets 17a, 17b. And the upper chamber 18e is provided with valve elements 18a1-18c1 whose lower end parts project into the lower chamber 18f in engagement conditions. And a switching lever 19 is rotated to rotate a rotating shaft 23 through a prescribed angle, thereby pushing up the valve discs engaged with the corresponding communicative ports to open the communicative ports by cams 23a-23c formed integrated to the rotating shaft 23 and to make the raw water inlet 15 communicate with any of the raw water feeding port 16 and the raw water outlets 17a, 17b.
