Product characteristics
1.In all kinds of valves, the flow resistance of the ball valve is the smallest. When the full diameter ball valve is opened, the sphere passage, the valve body passageway and the connecting pipe diameter are equal and become a diameter, and the medium can flow almost without loss.
2.The ball valve is rotated 90 degrees can be closed to open, open and close rapidly. Compared with the same gate valve, cut-off valve, small ball valve, light weight, easy to install the pipe
