Abstract: An eccentric butterfly valve that maintains high sealability when closed even when a high-pressure fluid is oriented in either direction of a forward flow or backflow. The valve includes a disk (23) axially supported at an eccentric position via a stem (22) inside a body (21). The disk is provided to a seat ring (24) fixed with a seat retainer (25) so as to be hermetically sealable. A flexible part is formed on an inner diameter side of the seat ring, and a spring member is mounted between the flexible part and the seat retainer. In the spring member, a load increases substantially in proportion to the magnitude of tilt of the flexible part when the disk is displaced to a seat retainer side. When the flexible part is elastically deformed, the spring member is elastically deformed in a state where contact with the seat retainer is avoided.
