A chevron-shaped seat portion is interposed between a valve body having a cylindrical fluid passage and a disc-shaped valve body rotatably supported within the valve body, and protrudes inward on the inner circumferential surface. In the seat ring of the butterfly valve, the inner diameter of the chevron-shaped seat part is formed into an arc having the same diameter as the outer diameter of the valve body and eccentric by the amount of bite at the center of the valve shaft, and is symmetrical about the valve shaft. A seat ring for a butterfly valve characterized by being formed into the shape of.
