Flanged butterfly valves are especially suitable for making large-diameter valves. They are widely used in the field of large-diameter regulation. When the flanged butterfly valve is fully opened, the flow resistance is small. When the butterfly plate is opened at an angle of about 15-70° At this time, the flanged butterfly valve can control the flow of medium very sensitively. In addition, because the butterfly plate of the flanged butterfly valve has wiping properties when rotating, this type of valve can be used in pipelines with suspended particle media. According to the strength of the seal, it can also be used for powder Shaped and granular medium pipeline. Classification of flanged butterfly valves: flanged butterfly valves can be divided into soft-sealed flanged butterfly valves and hard-sealed flanged butterfly valves according to the material of the sealing surface.Butterfly Valve Flange …
