勢するようにしたボールバルブ。 A valve ball having a through hole is arranged in a valve casing that forms a fluid passage, and the valve shaft is passed through the valve casing in an airtight manner to rotate the valve ball, and when it comes into contact with the valve ball, it opens and closes the fluid passage. In the case where an annular valve seat made of synthetic resin or synthetic rubber that works together with the valve ball is placed in the fluid passage, the annular valve seat is made of a temperature-responsive member such as a bimetal or shape memory alloy to keep the valve ball at a low temperature. A ball valve that is energized strongly at times and weakly at high temperatures.
