Large-diameter water supply and drainage valve will become a new growth point

With the increasing rate of urbanization in China and the rapid growth of urban population, the water supply of waterworks and the sewage treatment plant sewage treatment scale are gradually increasing, and the diameter of pipe network is increasing continuously. Therefore, a large number of large-diameter, large-diameter water supply and drainage valves are needed. . At the same time, various types of flood control, drainage, irrigation, water supply and drainage, hydroelectric power generation, water and soil conservation, water resources protection and other projects that have been incorporated into the management of water conservancy infrastructure are in great demand for all types of large-diameter, large-diameter water supply and drainage valves. The production capacity of large-diameter and large-diameter water supply and drainage valves in China cannot yet meet the growth in demand in the downstream market.

In the next few years, China will continue to speed up the implementation of the new three projects of the Huaihe River and the comprehensive management of Taihu Lake, Dongting Lake and Poyang Lake, and advance the major rivers and rivers such as the Ningxia and Mongolian reach of the Yellow River, river control in the middle and lower reaches of the Yangtze River, and add the “South-to-North Water Transfer Project”. "The development of the Century Project will continue to stimulate the scale of demand for various types of valve products, especially large-diameter gate valves, large-diameter turbine inlet butterfly valves, ultra-caliber turbine inlet ball valves, extra-caliber flow control valves, and extra-caliber vacuum valves. . As the production of large-caliber and ultra-large-diameter valves requires far more technical and technological requirements than ordinary valves, the added value of their individual products is high, which puts forward higher requirements for product design and processing levels.

At present, there are not many companies that can meet the requirements of domestic technology and equipment, while most of the other companies in the industry are mainly producing general-caliber valves. From the perspective of the entire industry, the production capacity of large-diameter water supply and drainage valves will show a steady growth trend. According to the statistical data of the valve branch of China General Machinery Industry Association, the sales proportion of large-diameter and large-diameter valves in the water supply and drainage sector is between 50% and 60%, taking the median value of 55%, and the market size from 2009 to 2011. They were 8.24 billion yuan, 9.55 billion yuan and 10.58 billion yuan respectively.
