A floating ball valve is a type of valve that uses a ball that floats on top of a liquid to control the flow of the liquid. The ball is connected to a lever that can be used to open and close the valve. When the valve is open, the ball floats, allowing the liquid to flow. When the valve is completed, the ball sinks and blocks the flow of the liquid. Floating ball valves are used in a variety of industries, such as oil and gas, chemical processing, and water treatment.

Floating ball valves are available in various materials, such as brass, stainless steel, and plastic. The material chosen will depend on the application in which the valve will be used.
