With the continuous development and widening of the application field of valves, the standard of valves corresponding to this valve is becoming more and more important. Therefore, we need to continue to make full use of the existing standards, at the same time, to study the new standards and new systems that can be used in the future, so as to promote the development of valve technology to a higher level, and continuously improve the level and grade of valve products.

At present, domestic valve production backbone enterprises have been able to design and manufacture various valves according to international standards such as ISO international standard, DIN German standard, AWWA American Standard, and some of the products of some manufacturers have reached the international advanced level. Valve is a product with low profit margins, and the market competition is fierce. Valve is an important fluid control equipment in industry. It involves many sectors of the national economy and is an important basic equipment for the development of national economy. In recent years, China's valve industry has developed very rapidly. The distribution of the valve market is mainly based on the construction of the project. The largest users of the valve are the petrochemical industry, the electric power sector, the metallurgical sector, the chemical industry and the urban construction department.

It is understood that China's valve manufacturing industry has been able to provide users with about twelve categories, more than 3000 models, more than 4000 specifications of the product, its performance parameters range from the vacuum valve to the 600Mpa ultra door, temperature from 196 degrees Celsius to high temperature 570 degrees Celsius. The main products of China valve have basically met the needs of the domestic market. The complete set rate, complete set level and complete set ability of the valve market have been greatly improved, and the domestic valves have already had a certain base of revitalization.

Although the development of the valve industry is stable for a long time, its competition is still not standard. The main problems are as follows: first, some operators buy the name and address of the manufacturer's name and address, or print famous manufacturer's famous brand and qualified certificate, misleading the consumer, and also cause serious harm to the reputation of the qualified valve enterprise. The two is that some operators make second sales after refurbishing and repainting the waste valves, which bring serious safety hazards to the quality of the engineering and seriously disrupt the order of the valve market.

Although the overall level of the valve industry in the past year has been greatly improved, but the quality is not stable, such as running, running, dropping, leakage phenomenon in domestic valves often appear. In addition, there is still a certain gap between China's valve supporting capacity and developed countries. Since last year, the localization of high-end valves has become very difficult. At present, the basic parts have become a short board to restrict the development of domestic manufacturing industry to the high-end. In 12th Five-Year, China's efforts on the localization of high-end equipment components will be further strengthened.

The development of China's valve industry is booming, but in the background of a good industry situation, some problems are also worthy of concern, especially the domestic valve enterprises mainly with low level, small scale, family workshop type enterprises. This is a great constraint and bottleneck for the future development of China's valve industry.

"The competition of the valve market is becoming more and more hot, the market of some common valve products has become saturated, and the supply of supply exceeds demand, which makes the development of small and medium-sized enterprises more and more difficult. Even those with relatively high technology content compete fiercely in the international market. Luo Baihui, the Secretary General of the International Die and hardware Plastics Industry Association, said that the current China has been able to provide a variety of products in the valve market, such as heating valves, environmental valves, and Building valves. But in the field of high pressure valves still rely on import, this is the future of China's valves need to force a breakthrough in the field, to truly promote the development of China's valve industry.

In the future, the valve market supply from a single variety to multi variety and multi specification development to meet the needs of complete sets of manufacturing projects, a enterprise manufacturing projects required by the valve, a growing trend from a valve manufacturer. I believe that China's valve industry will have a better development prospect under the huge demand environment.
