China's valve manufacturing enterprises are too small and the industry concentration is too low. According to statistics, there are currently more than 3,000 valve manufacturing companies in China, the number one in the world. However, most of them are low-level, small-scale, family workshop-type enterprises, with less than 500 companies with annual sales income of 5 million yuan, and only a dozen companies with annual sales revenue of more than 100 million yuan, with market share in the top 10. The combined market share of enterprises is only 8% -9%. Due to the low concentration of the industry, many disadvantageous factors such as backward technology, low price competition, and lack of influential brands have been caused. The main problems in the valve market are as follows: 1. Some operators buy inferior valves for the sake of profit, print the nameplates and certifications of well-known manufacturers, and cause serious damage to the reputation of qualified valve companies. Second, the refurbished valve, very few operators through the second sale after repainting the waste valve, bring serious safety risks to the project quality. How to transform domestic valve products in the future should start from the following points: 1. The market trend of cast steel valve products is shifting to oilfields and offshore oilfields with the development of oil, and the power industry is shifting from thermal power below 300,000 kilowatts to over 300,000 kilowatts. For the development of thermal power, hydropower and nuclear power, valve products should also change their performance and parameters according to changes in the application field of the equipment. 2.Urban construction systems generally use a large number of low-pressure valves, and have developed to be environmentally friendly and energy-saving, that is, the transition from low-pressure iron gate valves used in the past to environmental-friendly rubber plate valves, balance valves, metal-sealed butterfly valves, and center-line sealed butterfly valves. Oil and gas transmission projects are developing towards pipelines, which in turn requires a large number of flat gate valves and ball valves. 3. The other side of energy development is energy saving, so from the aspect of energy saving, it is necessary to develop steam traps and to develop subcritical and supercritical high parameters. 4. The construction of the power station is developing to a large scale, so large-diameter and high-pressure safety valves and pressure reducing valves are required, and quick opening and closing valves are also required. 5. For the needs of complete sets of projects, the valve supply has developed from a single variety to multiple varieties and specifications. The valve required for an engineering project is increasingly provided by a valve manufacturer. Regardless of whether it is short-term or long-term, the production of valve equipment has a very broad prospect. Especially with the help of four major factors: urban construction, industrial development, technological innovation, and globalization, China's domestic valve industry will develop in a more international, high-end, and modernized manner. The development direction of the domestic valve industry. Domestic valve equipment manufacturers are also in the process of continuously pursuing innovation, entering new markets, and seeking survival and development in the tide of the increasingly competitive pump and valve industry.
