butterfly valve flange type
The butterfly valve flange type is a crucial component in fluid control systems, characterized by its distinctive disc-shaped closure mechanism that rotates on a central axis. This versatile valve design incorporates standardized flanges on both ends, enabling seamless integration with existing piping systems while ensuring secure, leak-proof connections. The valve's construction typically features a resilient seated design with high-quality materials such as ductile iron, carbon steel, or stainless steel, depending on the application requirements. The flange connection follows international standards like ASME, DIN, or JIS, making it universally compatible across different industrial settings. The valve operates through a quarter-turn mechanism, where the disc rotates 90 degrees from fully open to fully closed positions, providing efficient flow control and regulation. The design incorporates special sealing elements that ensure tight shutoff capabilities, while the flange connection method facilitates easy installation, maintenance, and replacement procedures. These valves are particularly valued in applications requiring frequent operation, moderate pressure ratings, and the need for reliable flow control in both liquid and gas services.
