Introduction to Concentric Butterfly Valve
A concentric butterfly valve is a type of quarter – turn valve used to regulate or isolate the flow of fluid in a pipeline. It consists of a disc that rotates around a central axis perpendicular to the flow direction. When the valve is fully open, the disc is parallel to the flow, allowing maximum flow through the pipeline. When the valve is closed, the disc is perpendicular to the flow, blocking the passage. Concentric butterfly valves are known for their simple structure, low cost, and relatively low pressure loss. They are widely used in various industries such as water treatment, chemical, power generation, and HVAC systems. Concentric Butterfly Valve
