can quickly cut off or turn on the medium inside the tube
The main feature of rotary ball valve is that it can be reliably closed not only in the forward pressure, but also in the reverse pressure or the reverse pressure is much greater than the forward pressure. On the two sealing surfaces of the sealing pair, according to different hardness needs, advanced processes such as space plasma spraying, ether laser sputtering and vacuum protection infiltration surfacing can be used to form gradient functional materials such as martensitic stainless steel, austenitic stainless steel, cemented carbide, cermet and artificial diamond. It can align the center automatically and compensate the wear automatically. When closing, make full use of the energy of the medium in the rotary ball valve to automatically apply a very high sealing specific pressure, so that the high hard sealing pair can achieve reliable zero leakage. There is no friction between sealing pairs when closing and opening instantaneously. The main structure of the rotary ball valve is similar to that of the butterfly valve, which has the characteristics of short structure and small volume. Therefore, it can manufacture extra large diameter and extra large diameter valves
