flange fixed ball valve is one of the Industrial Valves, it oxygen and flanged gate valve, flanged butterfly valve, pressure reducing valve belong to the same type of valve, the closing of the difference is that it is a ball, the ball goes around the center line of the body to open and close. Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. In recent years, the ball valve is widely used. Below small make up and share the advantages of the flange fixed ball valve and open a closed process:

a fixed ball valve, flange 1, the fluid resistance is small, the advantages of its resistance coefficient with section of equal length. 2, simple structure, small volume, light weight. 3, compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system. 4, easy to operate, open and close quickly, from open to close just rotate it 90 & deg; To facilitate remote control. 5, convenient maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient. 6, in the full open or full close, sphere and Industrial Valves seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. 7, wide applicable scope, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. Ball rotated 90 degrees in the inlet and outlet should be completely present spherical, thereby blocking flow.

ductile iron gate valve are all following the most compatible manufacturing regulations.
