Butterfly valves control fluid flow using a rotating disc mounted on a central shaft. They are compact, lightweight, and require less installation space compared to other valves. These valves are ideal for large-diameter pipelines and high-volume flow applications. Butterfly valves allow quick operation with minimal effort. They are widely used in water treatment plants, HVAC systems, and fire-fighting lines. Their design supports both on-off and throttling operations. Butterfly valves offer cost-effective solutions for large systems. They provide good sealing and long service life.
