With the continuous and rapid development of our national economy, very urgent requirements are put forward for our energy industry. At present, China has formulated a policy based on thermal power, vigorously develop hydropower, and moderately develop new energy sources, such as nuclear power and wind power. The construction of nuclear power in China is changing from experimental and compensatory adjustment to strategic and aggressive development. This is a good development opportunity for China's nuclear power industry, and the demand for nuclear power plant valves has brought broad market prospects to domestic and foreign valve manufacturers.
