Cast Iron Butterfly Valve

A cast iron butterfly valve is a type of valve used to regulate the flow of liquids and gases. It is a quarter-turn valve, meaning it uses a quarter turn of the handle to open or close the valve. The valve is composed of a disc-shaped butterfly plate that is mounted on a rod. When the valve is closed, the disc blocks the flow of the liquid or gas. When the valve is opened, the disc rotates, allowing the flow to pass through. Cast iron butterfly valves are used in a variety of applications, including water and wastewater treatment, chemical processing, and oil and gas production.
