摘要： A butterfly valve includes a valve housing (1) having a substantially cylindrical flow passage formed therein, a disc-shaped valve element (4) arranged in the flow passage so as to be rotatable therein, a stem (3) extending from the valve element (4) to its outside and supported by the valve housing (1) so as to be rotatable, and an operating unit (8) for rotating the stem (3). The rotation of the stem (3) rotates the valve element (4) in the flow passage to open and close the flow passage. A top flange (2) for mounting the operating unit (8) is formed integrally with the valve housing (1). The top flange is formed with a plurality of cutouts (12) extending from the outer peripheral edge of the top flange toward the center thereof.
