Nuclear core island valves pass CIAE and NPIC tests

2010 and 2020, which require more than 30,000 valves for each unit, of which over one-third are used in the core island, while accounting for approximately 70 per cent of the total value. Each nuclear power generating unit will require valves for an amount of more than RMB350mn at core inland, of which imports have traditionally accounted for the majority. “Following the successful tests, we believe we are well-positioned to win orders in the nuclear core island valve market,” commented Mr Jianbao Wang, chief executive officer of China Valves. “Meanwhile, we have continued to make progress in supplying valves for the conventional island of nuclear power plants. We believe power generation will remain a growth driver for the upcoming years. In addition to nuclear valves, our strong competitive advantages include extra large diameter ball valves. We are the only company in China able to produce the large diameter ball valves for pumped storage hydropower plants, which are built with nuclear plants.” China Valves Technology Inc – China ir@cvalve.com www.cvalve.com

China Valves Technology, Inc, through its various subsidiaries, is engaged in the development, manufacturing and sale of high quality metal valves for the electricity, petroleum, chemical, water, gas and metallurgy industries. The company has announced that its gate and check valves used in the core island of nuclear power plants have suc- cessfully passed all tests administered by China Institute of Atomic Energy (CIAE), the primary nuclear science and technology research institute in China, and Nuclear Power Institute of China (NPIC), the leading base in China for nuclear reactor engineering research, design, testing and operation. With a diameter of 250mm and 1,500lb of compressive resistance, the prototype valves are among the largest and highest performing valves to be made by Chinese manufacturers. China Valves said that it has become the only

valve manufacturer in China to pass all tests provided by these two institutes at the first attempt, and the company is now eligible to supply valves for core islands of nuclear power plants, which are mostly imported from overseas. The valves underwent detailed tests, including functional tests and an earthquake test. The functional tests consist of a working life test which examines the valves resistance under 20 MPa high pressure at 38°C, repeated 500 times, and under extreme temperatures in the range of 316°C under pressure of 16 MPa, repeated 1,500 times, as well as impact tests under different temperatures, a high-pressure blocking test, a flow coefficient test and a pipe loading test. According to the National Development and Reform Commission (NDRC), China will install at least eight nuclear power generating units each year between
