What is a ball valve used for?

A ball valve is a type of valve that uses a ball-shaped disk to control the flow of fluid through a pipe. The ball has a hole through the center that can be aligned with the flow of fluid to allow it to pass through or blocked to stop the flow. Ball valves are commonly used in industrial and commercial applications to control the flow of liquids, gases, and slurries. They are known for their durability, ease of operation, and ability to handle high-pressure and high-temperature applications.
