　　" referred to as "SUFA".

　　At the beginning of the company's listing

　　Thousands of nuclear power grade valves for Phase I, Phase II and Phase III of Qinshan Nuclear Power Company and tens of thousands of valves for high temperature and high pressure power stations for nuclear power field, thermal power and thermal power projects. To become the leading enterprise in China's valve industry, with more than 500 domestic and foreign customers.
