The axial center of the valve stem is simultaneously deviated from the center of the disc and the center of the body, and the rotation axis of the valve seat has a certain angle with the axis of the valve body passage, which is called a three-eccentric butterfly valve. It is widely used in metallurgical, electric power, petrochemical, and industrial pipelines such as water supply and drainage and municipal construction with medium temperature ≤ 425 °C for regulating flow and load-carrying fluid.The advantage is that compared with the butterfly seat, the chance of the valve seat directly contacting the medium is greatly reduced, thereby reducing the degree of erosion of the valve seat and prolonging the service life of the valve seat.
