Gear Operated flange ball valve, as a kind of valves, is widely utilized in petrochemical industry and long-distance transport pipes. The closing part of ball valve is a ball with a hole. The ball turn 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 valve opened completely, the channel of the ball and valve body is equal to pipes, so that medium pass through without any loss. Compared with gate valve and globe valve, ball valve has small volume, light weight and convenient installment.
