Abstract
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 into a valve chamber in a valve casing to flow out of two outlet ports and Valve seats and communicating with the respective outlet ports are provided to opposite walls of the valve chamber facing each other and a poppet-type valve body 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 and provided to inner bottom portions of valve seat holes and having depths in which at least a half of a thickness of the valve body at a periphery of the valve body is embedded and suppresses reduction of the flow coefficient.
