Flanged butterfly valves

A butterfly valve is a fitting that serves to cut off or regulate the flow of the medium by rotating the blade located inside the body (shut-off or control butterfly valves). A wafer-type butterfly valve is placed between the two flanges of the pipeline. Among the butterfly valves, there may be centric one with a soft or metal/metal seal, double or triple eccentric butterfly valves, controlled by a manual lever drive, with a worm gear, with an electric or pneumatic drive.
