A ball valve is a type of valve that controls the flow of fluids through a pipeline using a spherical ball with a hole (or port) through its center. When the valve handle is turned, the ball rotates, aligning the port with the flow path to either open or close the valve. In the open position, the fluid flows freely through the valve, while in the closed position, the ball blocks the flow. Ball valves are known for their reliability, durability, and quick operation. They are often used in applications where a tight seal and low pressure drop are required, such as in water, oil, and gas systems. Their simple design makes them easy to maintain and suitable for high-pressure and high-temperature conditions
