Yongjia County Yinpei Valve Factory
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.
