Basic Introduction
Precision machining of valve balls adds ultra-precision grinding, mirror polishing, and other steps on top of CNC machining. Through multiple precision processes, strict control of spherical roundness, surface roughness, and geometric tolerances achieves ultra-high sealing surface accuracy and extremely low surface roughness, ensuring zero leakage sealing and low operating torque. Its high-precision characteristics are especially suitable for high-pressure, high-frequency operations and demanding zero-leakage conditions, widely used in high-end industrial valves, fine chemicals, and precision fluid control systems.
