This series provide Zero-leakage ball valves in several service applications with high temperature and/or high pressure. The ball and seat are hard coated with chrome carbide or tungsten carbide, which has high erosion and abrasion resistance, using KOSO-owned HVQF coating system. They are mate-lapped on our own technique to ensure fully sealing. Live loading also ensure zero emissions.
The ball never leaves the seat and wipes contaminants away. This self-cleaning action prevents the interference and damage from contaminants.
The valve is suitable for the slurry service and abrasive service.
