StainlessCarbonMild Steel Ball Valve is a quarter-turn rotational movement valve that uses a ball-molded circle to stop or begin stream. In the event that the valve is opened, the ball pivots to a point where the gap through the ball is in accordance with the valve body gulf and outlet. In the event that the valve is shut, the ball is pivoted so that the gap is opposite to the stream openings of the valve body and the stream is halted.
