Introduction to Manual Butterfly Valve
A manual butterfly valve is a type of quarter - turn valve that uses a disc to control the flow of fluid through a pipe. The disc is mounted on a shaft, and when the valve is opened or closed, the disc rotates a quarter - turn (90 degrees) to either allow or block the flow. Manual butterfly valves are widely used in various industries such as water treatment, HVAC (Heating, Ventilation, and Air Conditioning), chemical processing, and power generation due to their simple structure, low cost, and quick operation. They are available in different materials, including cast iron, stainless steel, and carbon steel, to suit different working conditions and fluid types.
