Introduction to Butterfly Valves
A butterfly valve is a type of quarter - turn valve that controls the flow of a fluid. It consists of a circular disc that rotates around a central axis within a pipe. When the disc is parallel to the flow direction, the valve is fully open, allowing maximum fluid passage. As the disc rotates perpendicular to the flow, the valve closes, restricting or completely blocking the flow. Butterfly valves are widely used in various industries such as water treatment, oil and gas, chemical processing, and power generation due to their simple design, low cost, and quick operation.
Now, let's take a look at the top 10 butterfly valve manufacturers in the world in 2025.
