Product Overview
Manual flanged ball valve is mainly used to cut off or put through the medium, can also be used for fluid regulation and control.Compared with other valves, ball valves have the following advantages:
1, the fluid resistance is small, the ball valve is one of the least fluid resistance in all valves, even if it is a reduced diameter ball valve, its fluid resistance is quite small.
2, the switch is fast and convenient, as long as the stem rotates 90°, the ball valve will comple...
