In 1968, some Yongjia natives working elsewhere brought back the first batch of valve business from Tianjin, marking the beginning of Yongjia County’s enduring valve industry. In 1973, Wang Hanzhou, along with Huang Mingjin and others from Oubei, began exploring valve production technology based on market demand. From 1969 to 1973, the development of Yongjia’s pump and valve industry was slow; some collective enterprises in Oubei and Shangtang in the county seat were merely exploratory in valve production. In June 1984, Wang Hanzhou and Huang Mingjin started with 3,000 yuan and founded the Yongjia County Qingshuibu Instrument Valve Factory, beginning the production of general-purpose valves. That year, its output value exceeded 50,000 yuan. Due to market recognition of its quality, the Yongjia County Qingshuibu Instrument Valve Factory expanded. In 1989, it was renamed the Yongjia County Yinpei Valve Factory, establishing partnerships with several large domestic steel companies. While producing valves to match imported equipment, it optimized valve structure, service life, and sealing performance, continuously developing distinctive valve products. In 1999, Zhejiang Chaoda Valve Co., Ltd. was established with Yongjia County Yinpei Valve Factory as its core. Wang Hanzhou served as chairman. Through the shareholding system, the management rights and ownership

In 1984, Wang Hanzhou and Huang Mingjin partnered to establish the “Yongjia County Qingshuibu Town Instrument Valve Factory No. 2”. In 1989, the company was renamed “Yongjia County Import and Export Valve Factory,” specializing in the production of valves for imported equipment and undertaking the localization of imported valves. Initially, the company was small-scale and lacked the capacity for large-scale production. Producing general-purpose valves on a small scale would have been economically unprofitable; therefore, the company focused on orders with specific customer requirements. At that time, some domestic petrochemical and steel companies imported their production lines from abroad. The valves used in these imported systems were expensive, and procurement and maintenance were difficult. Therefore, users urgently needed to localize imported valves. Chaoda seized this opportunity, leveraging its expertise in foreign valve standards, information, and technology to develop various domestically produced valve products that met the specific operating conditions of its customers. In the late 1990s, with the increase in overseas labor costs, foreign valve companies urgently needed to find valve companies with lower labor costs and better technology to cooperate with. With its strong technical strength, it gradually gained recognition from domestic valve users. Through more than ten years of

Founded in 1984, Zhejiang Chaoda Valve Co., Ltd. was upgraded to Chaoda Valve Group Co., Ltd. in May 2013. With a registered capital of 136.88 million yuan, a factory area of ​​32,566 square meters, and 552 employees, the company is a national high-tech enterprise, a vice-chairman unit of the China Valve Association, a member of the first-tier supply network for high and medium pressure valves for Sinopec, CNPC, and CNOOC, and a AAA-rated taxpayer in Zhejiang Province. The “Chaoda” brand valves have won titles such as Zhejiang Famous Trademark, Zhejiang Famous Brand Product, and Zhejiang Export Famous Brand. The company mainly produces high-parameter special wear-resistant ball valves, special metal hard-seal ball valves for ash water, black water, and coal slurry, cryogenic valves, bellows valves, slag-locking valves for coal gasification units, combination three-way valves, and other special valves, as well as ball valves, gate valves, check valves, globe valves, and butterfly valves conforming to ANSI/API, BS, DIN, JIS, and GB standards. Product technology is primarily developed independently, while actively engaging in industry-university-research cooperation with research institutes and universities. Our products are widely used in industries such as petroleum, refining, natural gas, chemicals, polysilicon, metallurgy, and power, and are exported to Europe,

In 1984, Wang Hanzhou and Huang Mingjin partnered to establish the “Yongjia County Qingshuibu Town Instrument Valve Factory No. 2”. In 1989, the company was renamed “Yongjia County Yinpei Valve Factory”, specializing in the production of valves for imported equipment. Extra-large diameter safety valves and negative pressure safety valves were used in coking projects at Shijiazhuang Coking Plant, Panzhihua Iron and Steel Group, and Maanshan Iron and Steel Group, replacing imports. In 1992, the company successfully registered the “Chaoda” trademark, aiming to “surpass ourselves through continuous innovation and meet the needs of high-end customers”. It produced API standard gate valves, globe valves, and check valves, exporting them to Japan through Shanghai Minmetals Corporation. In 1995, Qiu Xiaolai, deputy director of the Valve Department of the Hefei General Machinery Research Institute of the Ministry of Machinery Industry, joined the company, establishing a valve research laboratory. In 1996, Ning Danfeng, chief engineer of Lanzhou High Pressure Valve Factory, joined the company to implement a quality management improvement project. In 1997, a website with the domain name [domain name missing] was established. In 1998, a corporate technology research center was established, specializing in the development and research of new valve technologies and products.
