Founded in 1979, Shenjiang Valve Co., Ltd. is a national high-tech enterprise specializing in valve research and development, design, manufacturing and sales. The company is located in Zhejiang Province, with a registered capital of 120.08 million yuan and an area of 68,000 90,000 square meters. Relying on advanced equipment, sufficient industrial resources, integrated supply chain, and excellent processing and testing capabilities, the company's designed production capacity is 25,000 tons annually.
Committed to providing a complete set of industrial valve solutions for customers in the fields of petroleum, natural gas, oil refining, chemical industry, power plants, nuclear power, long-distance pipelines and other industrial field, our products are mainly designed and developed in eight series of gate valves, ball valves, butterfly valves, globe valves, check valves, plug valves, flat valves and regulating valves, covering low temperature, ultra-low temperature, high temperature, bellows, sulfur resistance, hydrogen resistance, wear resistance, low leakage, full vacuum and other industrial applications.The valve design and manufacture standards adopted mainly refer to GB, ANSI, ASME, API, DIN, BS and JIS. The maximum diameter of the valve can reach 160" (DN4000), the maximum pressure can reach 20000PSI (138MPa), and the minimum temperature is -196 ℃, the maximum temperature Reaching 750℃.
In addition to the excellent human resources of 68 technicians and engineers, which almost cover all the technical subjects including material, machining, process, welding, heat treatment, testing, financial management, human resource management, etc., the company is equipped with advanced first-class processing and inspection equipment to build up a solid foundation for guaranteed quality. Except the platforms used for routine experiments such as low temperature test, low leakage test, API624 high temperature and low leakage test, fire protection test, valve cold and hot state test system, ultra-high pressure test system, etc., we have the only valve flexible manufacturing system (FMS) assembly line in China, 12 CNC vertical lathes of 5m, 3.5m and 2.5m , CNC floor boring and milling machines of 200mm, 130mm , 8 imported machining centers from Japan and Taiwan and Shenyang, are more than 50 sets of CNC machine tools produced in Changzhou and other places, as well as nearly 700 sets of high-precision machining and inspection equipment such as γ and X-ray flaw detection, three-coordinate measuring instruments, and elemental analyzers.
Quality is the life for manufacturing. Perfect quality management system and advanced inspection capabilities can effectively ensure product quality. In 1989, the company passed the acceptance of standardization, measurement and total quality management; in 1996, the company fully introduced ISO9002 "Quality System Quality Assurance Mode for Production, Installation and Service" and obtained ISO9002 certificate; in 1998, it passed the certification of American Petroleum Institute; ISO9001 certificate issued by Det Norske Veritas, and successively passed EU CE/PED certification, API 600 certification, API 6D certification, API 608 certification, API 594 certification, API602 certification, ISO14001 environmental management system certification, ISO45001 occupational, health and safety management System certification, special equipment manufacturing license (TS2710192-2025), and obtained the national civil nuclear pressure equipment design and production qualification license in July 2007.
These strong support earns SJV a wide market all over the world. About 50% of the valves are exported to more than 20 countries including the United States, Italy, Spain, Russia, Iran, Iraq, Kuwait, the United Arab Emirates, Brazil, Argentina, etc. After more than 40 years of development, Shenjiang has developed into one of the backbone valve manufacturers in China, and "Shenjiang" trademark was rated as a well-known trademark in Wenzhou City. The company is now the deputy director unit of the Valve Branch of China General Machinery Industry Association, the vice chairman unit of Wenzhou Pump and Valve Association, a member unit of China Petrochemical Corporation's resource market, and a member of China National Petroleum Corporation. It is also a member unit of the first-level network supplier network, a member unit of China Petroleum Energy Network, a member unit of CNOOC, a member unit of China Shenhua Network, and an excellent supplier of domestic large petrochemical enterprises such as Fujian Petroleum Refining and Ethylene, Shanghai Secco, Shenhua, Sinopec, Gulei, etc. In terms of nuclear power, it has the qualification license for the design and manufacture of civil nuclear pressure equipment in China, and is a qualified sub-supplier of Qinshan Nuclear Power, CNNC Eastern Engineering Company, CNNC Fifth Company and other enterprises. Over the years, it has been awarded the honorary titles of "advanced enterprise", "key backbone enterprise", "export earning enterprise", "large taxpayer" and "excellent manufacturer" by governments at all levels.
Advanced design concept and Strong design capabilities, rich industrial resources and first-class processing, high-end equipment and inspection & testing capabilities, perfect quality management system and a united and cooperative work team , all of these factors effectively ensured the product quality, and will keep on providing complete solutions for the petrochemical industry all over the world.
