Butterfly Valve, Grade : Manual

A butterfly valve is a quarter-turn rotational valve used to regulate flow in pipelines. It features a circular disc or vane that pivots on a shaft to open or close the valve. When the valve is open, the disc is parallel to the flow, allowing fluid to pass through with minimal resistance. When closed, the disc rotates perpendicular to the flow, creating a tight seal. Butterfly valves are known for their compact design, lightweight construction, and quick operation. They are commonly used in applications such as water treatment, HVAC systems, and chemical processing due to their reliability and ease of maintenance. Available in various sizes and materials, butterfly valves offer efficient flow control and are suitable for both high and low-pressure systems.
