In industrial fluid transmission, complex media such as strong acids and alkalis, solid-containing particulates, and cryogenic temperatures pose extreme challenges to valves. Relying on material innovation and structural customization advantages, OUWEI ball valves build a full-scenario medium adaptation system, becoming a universal fluid control solution for multiple working conditions. For strong corrosive media, OUWEI lined fluoroplastic ball valves adopt PTFE/PPL lining technology, resistant to 98% concentrated sulfuric acid, 50% sodium hydroxide and other media, with a corrosion rate of ＜0.01mm/year; ball valves made of 316L stainless steel and titanium alloy perfectly meet the chloride ion corrosion resistance requirements of marine environments and pharmaceutical pure water systems. For handling particulate-containing media such as mineral slurry and paper pulp, the shear notch design of OUWEI V-port ball valves achieves a 98% particulate passing rate, extending the valve seat wear cycle to 18 months; full-bore ball valves reduce medium scouring through equal-diameter flow channels, with a pressure drop 65% lower than that of globe valves. Facing -196℃ liquid nitrogen and LNG cryogenic working conditions, OUWEI cryogenic ball valves adopt long neck bonnet and austenitic stainless steel materials to eliminate cryogenic brittle failure. The full range of OUWEI ball valves covers a nominal diameter of DN6~DN800 and an operating temperature of -196℃~680℃, providing stable protection for the transmission of complex media in petroleum, chemical, energy and other industries.
