Science and technology are the primary productive forces, which reflects the role of an enterprise's innovation in enterprise development from the side. This is also true in the solenoid valve industry with strong market demand. The solenoid valve industry in China started late and basically relied on imports before the 1990s. In the late 1990s, Chinese solenoid valve manufacturers began to introduce foreign advanced technology and improve their innovation and manufacturing capabilities, so that the Chinese solenoid valve industry embarked on a path of independent innovation and self-sufficiency. As a representative enterprise of high-end solenoid valves, Shanghai Dongfeng Valve has been able to develop and rise rapidly, which also represents a microcosm of the solenoid valve industry.

Shanghai Dongfeng Valve is a well-known high-end control valve manufacturer in China and a national high-tech enterprise. After 20 years of technology precipitation and accumulation, Dongfeng Valve has grown into an enterprise with its own core technology, independent research and development, and continuous innovation, and embarked on a "smart" manufacturing road of high-end solenoid valves.

The predecessor of Shanghai Dongfeng Valve is Shanghai Zhenliang Valve Factory. The development time can be traced back to 1996. Since then, it has begun to produce automatic control valves. In 2003, the company began to carry out equity restructuring and changed its name to Shanghai Juliang Solenoid Valve Manufacturing Co., Ltd. At the beginning of the name change, Dongfeng Valve was determined to become a first-class Chinese control valve enterprise through its own continuous innovation and research and development, change China's dependence on imports, provide high-quality high-end products for all walks of life in China, and make contributions to social progress.

In the process of development, Juliang, on the one hand, has continuously invested in R&D resources, established R&D centers, and created its own products with intellectual property rights and core competitiveness; On the other hand, Dongfeng Valve began to introduce advanced western solenoid valve production process and technology, strengthen technical exchanges and strategic cooperation with advanced countries, absorb the essence and remove the dross, and complete the research, development and production of a series of cutting-edge control valve products. Up to now, Dongfeng Valve has successively obtained ISO9001 certification, national high-tech enterprise, national special equipment manufacturing license certification, etc., and the current chemical plant of 20000 square meters in Shanghai Songjiang Industrial Park has been approved by the government and put into operation. After years of technology precipitation and innovation, Shanghai Dongfeng Valve has become the representative of domestic high-end control valve manufacturers.

In recent years, the products produced by Dongfeng Valve have been widely used in many key large-scale projects across the country, including CSR, China Shipbuilding Industry, China Aerospace Science and Technology, Shuangliang Co., Ltd., etc., and have established good cooperation relations with many key enterprises and engineering projects across the country. Dongfeng Valve's products are not only sold all over the country, but also exported to overseas markets, and embarked on an international development path.
