Main features: The center of the butterfly valve stem and the center of the butterfly plate intersect perpendicularly with the centerline of the valve body and pipeline When closed, the outer sealing surface of the butterfly valve will squeeze out the synthetic rubber valve seat, causing elastic deformation on the valve seat and ensuring the sealing performance of the butterfly valve from the surface. It has been widely used in many fields such as petroleum, chemical, metallurgy, hydropower, etc.
