The disc of the centerline butterfly valve aligns with the centerline of the valve stem. The disc is relatively thick, providing better sealing performance. The centerline butterfly valve is mostly used in low-pressure, normal temperature fluid pipeline systems. The turning axis of the butterfly plate is located on the centerline of the valve body and the butterfly plate sealing area. When closed, the outer sealing surface of the butterfly plate compresses the synthetic rubber valve seat, causing elastic deformation of the valve seat, thereby ensuring the sealing performance of the butterfly valve.
