Multiple way valve

摘要

A 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 outlet ports are provided in 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 13 and 31 to connect the inlet port 41 to one of the outlet ports 42 and 43 and to close the other of the outlet ports is disposed in the valve chamber 12. The valve seats are recessed in the valve chamber 12 and provided at inner bottom portions of valve seat holes 17 and 18 having depths of at least half of the thickness of the valve body 5 at a periphery of the valve body 5 to prevent reduction of the flow coefficient. The three-port fluid selector valve has a large flow coefficient but compact structure.
