Flanged Butterfly Valve – Cast Steel / Stainless, Class 150-300, Chemical Processing, CE

The flanged butterfly valve is a core product in the butterfly valve category that employs a flanged connection method. It operates by rotating the disc 90° around the valve stem to achieve pipeline opening/closing and flow regulation. The key feature is the integrated flanges at both ends of the valve, which are secured to pipeline flanges via bolts. This product combines reliable structure, excellent sealing performance, and convenient installation/maintenance. It is suitable for medium-high pressure, large-diameter, and frequent operation scenarios in industrial and municipal applications, making it one of the most widely used control valves in pipeline systems.
