2025 Best 10 Butterfly Valve Factory in the world

Introduction to Butterfly Valve

A butterfly valve is a type of quarter - turn valve that regulates the flow of a fluid. It consists of a disc mounted on a rotating shaft. When the valve is fully open, the disc is parallel to the flow of the fluid, allowing for minimal obstruction and high flow rates. When the valve is closed, the disc is perpendicular to the flow, preventing the passage of the fluid.

Butterfly valves are widely used in various industries such as water treatment, chemical processing, power generation, and HVAC systems due to their simple structure, low cost, and quick operation. They are available in different sizes, materials (such as cast iron, stainless steel, and PVC), and designs (such as concentric, double - eccentric, and triple - eccentric) to meet different application requirements.
