Butterfly valves are a modern alternative to traditional gate valves, utilizing micro-scale deformation from the flexible disc to achieve superior sealing performance. The advantages of soft-seal butterfly valves include lightweight design, reliable sealing, flexibility, and extended service life. These valves are widely used in various industries such as water supply, wastewater treatment, construction, oil, chemical, food, pharmaceuticals, textiles, electrical systems, marine applications, metallurgy, and energy systems. They are ideal for use in fluid pipelines as control and shut-off devices.
