Fixed ball valve door have those advantages

Flange fixed ball valve door is a kind of gate valve, flange butterfly valve and flanged gate valve door, door, it belong to the same type of oxygen and pressure relief valve gate valve, the closing of the difference is that it is a ball, a sphere around the center line of valve body rotation to open and close. Ball valve in the line is mainly used to do to cut off the door, distribution, and change the flow direction of medium. Is widely used in recent years, the ball valve gate. Below small make up and share the advantages of lower flange fixed ball valve door and open closed process: a, the flange fixed ball valve gate 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 the door materials, sealing is good, have 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, ball valve gate structure is simple, sealing ring, which generally remove replacement is more convenient. 6, in the full open or full close, sphere and valve 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.
