Gear Operated Flange Ball Valve, as a kind of valves, is widely utilized in the petrochemical industry and long-distance transport pipes. The closing part of the ball valve is a ball with a hole. The ball turns with the stem to open or close the valve. Compared with other valves, the flow resistance of gear operated flange ball valve is minimum. When the valve opened completely, the channel of the ball and valve body is equal to pipes, so that the medium pass through without any loss. Compared with the gate valve and globe valve, a ball valve has a small volume, lightweight and convenient installment.
