Key advantages of stainless steel three-piece vacuum ball valve
These advantages make the stainless steel three-piece vacuum ball valve play an important role in various fields that require accurate control of the vacuum environment, especially in scientific research, semiconductor manufacturing, flat panel display manufacturing, solar cell manufacturing and vacuum coating.
(1) Small fluid resistance:
The resistance coefficient of the stainless steel three-piece vacuum ball valve is equal to that of the pipe section of the same length, which is conducive to maintaining the continuity and stability of fluid flow.
(2) Simple structure, small size and light weight.
(3) Sealing Surface Isolation in Fully Open/Closed Ball Valves:
When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium: when the medium passes through, it will not cause erosion of the valve sealing surface, which helps to extend the service life of the valve.
(4) Vacuum welding technology:
It mainly reflected in the welding process, the valve forms a strong and sealed weld during the manufacturing process, which improves the overall strength and sealing performance of the valve.
(5) Precision ball design:
The ball surface has been specially treated and has excellent wear resistance and corrosion resistance. The ball and the valve seat fit tightly to achieve zero leakage.
(6) Maintainability and interchangeability:
Since the valve adopts a modular design, the various components can be easily disassembled and replaced, reducing maintenance costs.
