ball valve

A ball valve is a type of valve that uses a rotating ball with a hole through its center to control the flow of liquid or gas. When the hole is aligned with the flow direction, the valve is open; when the ball is rotated 90 degrees, the flow is blocked.

Ball valves are commonly used in plumbing systems, gas and oil pipelines, industrial processes, and HVAC systems due to their durability and reliable shutoff capabilities.
