Introduction to Butterfly Valves
Butterfly valves are a type of quarter – turn valve used to regulate and control the flow of fluids (liquids or gases) in a pipeline. They consist of a disk mounted on a shaft that rotates inside the valve body. When the valve is fully open, the disk is parallel to the flow of the fluid, allowing maximum flow. As the valve is closed, the disk rotates until it is perpendicular to the flow, effectively blocking the passage and stopping the flow. Their simple design, relatively low cost, and quick operation make them popular in a wide range of industries, including water treatment, chemical processing, power generation, and food and beverage.
