Coating

 To endow ball and seat surfaces with exceptional wear resistance, corrosion resistance, and  low friction coefficients, we utilize world-leading surface coating equipment. Our coating  processes are conducted in strictly controlled clean-room environments using advanced techniques like HVOF/HVAF spraying, ensuring strong coating-substrate adhesion, uniform thickness, and ultra-low porosity. This guarantees performance reliability in the most  demanding applications (e.g., petrochemical, nuclear power), significantly extending valve service life.
