Shenjiang Valve Co., Ltd. was founded in November 1979 and is a national high-tech enterprise specializing in valve research and development, design, manufacturing, and sales. The company is located in Leqing City, Wenzhou City, Zhejiang Province, on the coast of the East China Sea, with a registered capital of 120.8 million yuan. It covers an area of 68000 square meters, a construction area of 90000 square meters, and a designed production capacity of 25000 tons.

The company is committed to the design and development of valves in the fields of petroleum, coal chemical industry, chemical industry, natural gas, long-distance pipelines, nuclear power, marine engineering, thermal power, new energy, etc. As a member of the China Valve Expert Committee and a national standard drafting unit, the company has participated in the drafting of 15 standards, including "Technical Conditions for Low Temperature Valves", "Technical Conditions for Nickel and Nickel Base Alloy Castings for Industrial Valves", and "Steel Plug Valves". In 2018, with the approval of the Zhejiang Provincial Department of Science and Technology and the Economic and Information Technology Commission, the "Shenjiang Provincial Enterprise Research Institute for Large Caliber Special Valves in Zhejiang Province" and the "Shenjiang Provincial High tech Enterprise Research and Development Center for Large Flow Industrial Valves" were established. In 2021, the Zhejiang Postdoctoral Workstation was established to jointly carry out postdoctoral training work with Zhejiang University, Zhejiang University of Technology, and Dalian University of Technology. For forty years, we have been committed to core technology and product innovation research and development. The company currently has 53 invention patents and software copyrights for wear-resistant gate valves, ball valves, and control valves. We have in-depth research, design, and manufacturing capabilities in high-end valve products such as high-pressure hydrogenation valves, high acid medium valves, high-temperature and high-pressure valves, and ultra-low temperature valves, and have good performance. Our comprehensive technical level is in an advanced position in China.

The company has advanced management concepts and has introduced the concepts of standardization, metrology, and comprehensive quality management earlier in China. In 1998, it passed the certification of the American Petroleum Institute and became the first private valve manufacturing enterprise in China to obtain an API certificate. In 2000, the company established an advanced computer CAD/E studio, using internationally popular analysis and design software to achieve valve modular design, model analysis, finite element analysis, etc; In 2011, ERP (Enterprise Resource Management System) was introduced to achieve resource integration and business process management. At the same time, the company focuses on industry, academia, and research, focusing on breakthroughs in key technologies. It has conducted extensive cooperation with Zhejiang University, Shanghai Institute of Nuclear Technology, Lanzhou University of Technology, and Zhejiang University of Electronic Science and Technology in talent cultivation, new product development, basic research, and other areas.

The company has a strong technical force and currently has 68 engineering and technical personnel with complete expertise, covering materials, machining, processes, welding, heat treatment, testing, financial management, human resource management, etc. The company is equipped with first-class processing and inspection equipment, the only valve flexible manufacturing system (FMS) assembly line in China, 12 5-meter, 3.5-meter, and 2.5-meter CNC vertical lathes, 200mm and 130mm CNC floor boring and milling machines with spindle, 8 imported machining centers from Japan and Taiwan, and more than 50 CNC machine tools produced in Shenyang, Changzhou, and other places γ、 Nearly 700 sets of high-precision processing and inspection equipment, including X-ray flaw detection, three coordinate measuring instruments, and element analyzers. The company has advanced testing equipment and has established comprehensive testing platforms such as low-temperature testing, low leakage testing, API624 high-temperature and low leakage testing, fire prevention testing, valve cold and hot testing systems, and ultra-high pressure testing systems to meet the testing requirements of various valves.

Quality is the life of an enterprise, and the company has a comprehensive quality management system and advanced inspection capabilities. It strictly controls all aspects of product manufacturing to effectively ensure product quality. In 1989, the company passed the acceptance of standardization, metrology, and comprehensive quality management; In 1996, the company fully introduced the ISO9002 "Quality Assurance Model for Production, Installation, and Service of the Quality System" and obtained the ISO9002 certificate; Certified by the American Petroleum Institute in 1998; In 2000, he obtained the ISO9001 certificate issued by Det Norske Veritas, and subsequently passed the EU CE/PED certification, API 600 certification, API 6D certification, API 608 certification, API 594 certification, API 602 certification, ISO14001 environmental management system certification, ISO45001 occupational, health and safety management system certification, special equipment manufacturing license (TS2710192-2025). In July 2007, he obtained the National Civil Nuclear Pressure Equipment Design and Production Qualification License.
