摘要： A three-port fluid selector valve is formed to have a large flow coefficient while making a structure of the valve compact. This three-port fluid selector valve allows fluid which has flowed from an inlet port 41 into a valve chamber 12 in a valve casing 1 to flow out of two outlet ports 42 and 43. Valve seats 13 and 31 communicating with the respective outlet ports are provided to opposite walls of the valve chamber 12 facing each other and a poppet-type valve body 5 for being selectively seated on the valve seats to connect the inlet port to one of the outlet ports and to close the other of the outlet ports is disposed in the valve chamber. The valve seats are formed in recessed shapes in the valve chamber 12 and provided to inner bottom portions of valve seat holes 17 and 18 having depths in which at least a half of a thickness of the valve body 5 at a periphery of the valve body 5 is embedded and suppresses reduction of the flow coefficient.

摘要： There is provided a two-port valve in which a deviation of a degree of parallelization of a valve member and a valve seat can be corrected automatically, which has excellent airtightness, and in which assembly and replacement of the valve member are easy. For this purpose, a shoulder portion 51 and a small-diameter portion 52 are formed in a vicinity of an end portion of a shaft 15, a groove portion 55 into which a snap ring 54 is mounted is formed in a vicinity of a tip end portion of the small-diameter portion, a through hole into which the small-diameter portion 52 is inserted and an annular stepped portion formed by increasing a diameter of a portion of the through hole are provided to the valve member 25, a sealant 65 for providing sealing between the shaft and the valve member is mounted to the stepped portion, a plate 66 is provided between the valve member 25 and the snap ring 54, and the valve member 25 is locked while pressing the sealant 65 mounted to the stepped portion and while being pushed against the shoulder portion 51 by the snap ring 54 mounted into the groove portion 55 and the plate 66.
