Product features
1.The resistance coefficient is equal to that of the same length of pipe;
2. Simple structure, small volume and light weight;
3.At present, the sealing surface material of ball valve is widely used plastic with good sealing performance, and it has been widely used in vacuum system;
4.It is easy to operate, open and close quickly, from full open to full close as long as 90 ° rotation, convenient for remote control;
5. Easy maintenance, simple structure of ball valve, movable sealing ring, easy disassembly and replacement;
6. When the valve is fully opened or closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the erosion of the sealing surface of the valve will not be caused when the medium passes through;
7.It has a wide range of applications, ranging from small diameter to several millimeters, to several meters, from high vacuum to high pressure. When the ball rotates 90 degrees, the inlet and outlet of the ball should be spherical, so as to cut off the flow.
