DN500 Butterfly Valve

The DN500 butterfly valve is a pivotal component in fluid control systems, with a diameter roughly equivalent to 20 inches, designed to handle significant flow rates with precision. Named for its distinctive butterfly wing-like disc, this valve controls fluid flow within a pipeline through a quarter-turn rotation mechanism. The valve's design features a circular disc that pivots on a stem, aligning perpendicular to the flow when fully open, thus providing an unobstructed path for fluid. Conversely, when the valve is closed, the disc aligns parallel to the flow, effectively sealing off the passage.
