Introduction to Butterfly Valve
A butterfly valve is a type of quarter - turn valve that controls the flow of a fluid through a pipe. It consists of a circular disc, which is positioned in the center of the pipe. When the valve is fully open, the disc is turned so that it allows the fluid to flow freely. When the valve is closed, the disc is rotated 90 degrees to block the flow. Butterfly valves are widely used in various industries such as water treatment, oil and gas, chemical, and power generation due to their simple structure, low cost, and ease of operation. They are also known for their quick - acting capabilities, which makes them suitable for applications where rapid flow control is required.
