Suzhou Dongshan Anti corrosion Instrument Valve Co., Ltd. has been developing and producing anti-corrosion control valves since 1988. For more than 20 years, Mr. Zhou Qingnan, the factory director (current chairman), has led the entire factory staff to develop products such as fluorine lined plastic corrosion-resistant ball valves and butterfly valves, solving the problems of corrosion, running, emitting, dripping, and leaking that could not be solved by self-control valves used in acid, alkali, and toxic gas media such as chlorine gas in the past. This has filled the domestic gap and changed the previous situation of relying on imported valves, saving the country a lot of funds and foreign exchange. At the same time, Suzhou Dongshan Anti corrosion Instrument Valve Company started from scratch, with an annual output value of only tens of thousands of workshop style small factories, and has now developed into a high-tech enterprise with a registered capital of 10 million yuan, annual sales of more than 30 million yuan, and an annual tax payment of over 2 million yuan to the country. It is a well-known professional manufacturer of anti-corrosion self-control valves in China.
In June 2010, at the 6th National Congress of the China Industrial Anti corrosion Technology Association held at the China National Convention Center, Suzhou Dongshan Anti corrosion Instrument Valve Co., Ltd. was awarded the honorary title of National Innovative Enterprise in the Anti corrosion Industry, and its chairman Mr. Zhou Qingnan was honored as a leading figure in the national anti-corrosion industry enterprise (leader). By 2009, Mr. Zhou Qingnan, the chairman of the company, had applied for and obtained 4 national invention patents. In 2005, Mr. Zhou Qingnan himself was invited as a special guest to attend the 4th China Scientists Forum held at the Great Hall of the People in Beijing< br> At the same time, the product standard "Pneumatic lined Fluoroplastic Control Valve" formulated by Suzhou Dongshan Anti corrosion Instrument Valve Co., Ltd. has successfully passed the review of the expert group of the National Anti corrosion Standardization Technical Committee. Suzhou Dongshan Anti corrosion is the first unit in China to pass the national standard audit for this type of product.
At present, various anti-corrosion self-control valves produced by Suzhou Dongshan Anti corrosion Instrument Valve Co., Ltd. have been adopted by national key projects such as Daya Bay Nuclear Power Station and Jiangsu Lianyungang Nuclear Power Station, as well as more than 300 large and medium-sized enterprises in 28 provinces and cities across the country. Its products are exported to countries such as Japan, Germany, Russia, India, South Korea, Myanmar, Vietnam, Syria, Pakistan, and Taiwan, and applied to industries such as petrochemicals, pharmaceuticals, metallurgy, and electronics.
