Nanjing Huaning Valve Co. Ltd. has obtained ISO9000 system certification from the international DNV organization, API certification in the United States, and special product production licenses issued by the General Administration of Quality Supervision, Inspection and Quarantine of China. After the company restructured, it relied on its strong technical advantages, actively adjusted its product structure, and expanded domestic and international markets. Currently, it has developed high-parameter power station gate valves, globe valves, check valves, high differential pressure, high-performance, and large-diameter control valves that are in urgent demand in the market, including series SA105, WCB, WC6, WC9, C12A, F12 CL2, C12A, 12Cr1MoV, F22 CL3, and F91 series gate valve, globe valve, check valve, high pressure valve, large diameter control valve for power plant, taking solid steps toward the localization of high-end valves. Nanjing Huaning Valve Co. Ltd. valves have also evolved from supporting small power plant units and small power plants to gradually becoming a major valve manufacturer for large thermal power plant units with domestic substitution. From 100MW units to 1000MW units; from the boiler island, feedwater, and desuperheating water systems to the drainage, venting, sampling, high-pressure, main steam, and reheated steam systems across the entire power station.
