China Nuclear Su Valve Technology Industrial Co., Ltd. was formerly the Suzhou Iron Factory established in 1952 (later changed to Suzhou Valve Factory). It is a technology-based manufacturing enterprise integrating industrial valve research and development, design, manufacturing and sales. The company was in 1997. Listed on the Shenzhen Stock Exchange, becoming the first listed company to the China Valve Industry and China Nuclear Industry Group Co., Ltd. It has a professional industrial valve production base with a variety of varieties, complete specifications and high technical content in the domestic valve industry. It is a domestic industry in the same industry. It is an enterprise with complete certification certificates and advanced quality management and testing methods. The company currently has 10 holding subsidiaries and stakeholders, covering valve manufacturing, testing, nuclear technology application and finance.

The company adopts the principle of "creating value for shareholders, employees, enterprises and society", adheres to the market-oriented and international orientation, and provides valve systems for oil, natural gas, oil refining, nuclear power, electricity, metallurgy, chemical industry, shipbuilding, papermaking, medicine and other industries. The solution has gradually formed three mainstream target markets of "nuclear engineering, petroleum and petrochemical, and public engineering". It is a leading enterprise in the field of nuclear power valves in China and the main supplier of nuclear power valves of the three major domestic nuclear power groups. It maintains good relations with the "three barrels of oil" The strategic cooperation relationship and provides valve products to large private petrochemical enterprises such as Hengli Petrochemical and Zhejiang Petrochemical. It has a good reputation in the domestic valve industry and has a strong brand influence.

The company promotes independent innovation in the localization of key valves, successfully develops a number of key valves with international advanced levels, such as main steam isolation valves, completes major engineering tasks on schedule and maintains quality, and promotes the "country to advance" of key nuclear power valves, and strives to ensure nuclear power. The supply security, independent control, self-reliance and self-improvement of the energy industry chains in industry, petroleum, chemical, thermal power and other energy fields plays an important role in the supply security, independent control, self-reliance and self-reliance. The company's technological R&D strength and digital informatization level rank among the forefront of China's valve industry, and has been successively designated as the No. 1 by the National Development and Reform Commission.
