Analysis of Development Status of General Mechanical Valves

At present, the domestic valve production backbone enterprises have been able to design and manufacture various valves in accordance with international standards such as ISO International Standard, DIN German Standard, and AWWA American Standard. Some manufacturers' products have reached the international advanced level. Although the overall level of the New Year's valve industry has been greatly improved, but the quality is not yet stable, such as run, run, drip, leakage phenomenon often occurs in domestic valves. In addition, there is still a certain gap between China's valve supporting capabilities and developed countries.

China has become a manufacturing factory in the world and a major manufacturer of pump valves. It is reported that China has ranked first in the world in terms of total valve production for 10 consecutive years, with an average annual growth of 10.9%, covering automobiles, energy, machine tools, pipeline pump valves, aerospace, construction machinery and other industries. However, the industry is “large but not strong”, with small enterprises, low industrial concentration, unreasonable product structure, weak independent innovation capability, backward equipment and processes, and extensive development with high investment, high consumption, high pollution, low efficiency, and low efficiency. The method highlights that the industrial base remains fragile, especially in the high-end valve production field.

Machinery industry analysts pointed out that with the continuous pace of valve industry restructuring, the future competition between the valve industry enterprises will be the product quality and safety of valve products and the competition between product brands, products to high-tech, high parameters, resistant to corrosion, high Life direction development.

The domestic machinery and equipment manufacturing industry is actively seeking high-end development. If the import of important components still depends on imports, not only will a large amount of profits be swallowed up, but it will also be detrimental to the independent innovation of the industry. Therefore, the production level and product performance of domestic components such as valves will be improved. We must closely follow the market demand to better promote the domestic manufacturing industry to the high end.

It is reported that China's valve market turnover of up to 50 billion yuan, which fully shows the size and momentum of China's valve industry development. However, under the background of a good industrial situation, there are also some problems worth worrying about, especially the valve companies in China mainly focus on low-level, small-scale, and family-run enterprises. This is a big limitation and bottleneck for the future development of China's valve industry.

The market competition in the valve market has become increasingly fierce. Some ordinary valve product markets have become saturated and supply exceeds demand. This has made the development of SMEs more and more difficult. And even high-tech products are fiercely competitive in the international market. At present, in the valve market, China has been able to provide heating valves, valves for environmental protection, and valves for construction. However, in the field of high pressure valves still rely on imports, this is the future of China's valves need to make breakthroughs in the field, in order to truly promote the development of China's valve industry.

There are 12 factory-run research institutes in China, 2 professional research institutes, about 6,000 researchers engaged in product development and valve research, a department-level testing center and two sub-centers, capable of performing general-purpose valves, general-purpose valves, and steam traps. The performance test, but lack of dynamic simulation test means for test equipment, high performance parameters and high temperature parameters. The number of scientific research institutions in the valve industry is relatively small, and the capacity for scientific research and development is weak. The number of scientific research personnel is less than 10% of the number of employees. At present, some of them can only rely on some prototypes and structures from abroad to carry out some absorption and digestion work. There are also few real product development efforts.

Since last year, the road to localization of high-end valves has been “bumpy”. At present, the basic parts have become a shortcoming that restricts the development of China's manufacturing industry to high-end. During the 12th five-year period, the government will continue to increase the localization of high-end equipment components. Here we have selected several representative valves in key development industries mentioned in the “Implementation Plan” to conduct feasibility analysis of import substitution (eg petroleum, power stations, metallurgy, machinery, electronics, mining, chemicals, building materials, electricity, energy , sewage treatment, etc.). From the analysis we can see that the sub-industry's valve import substitution is very different. The high-end valve needs more government.

Problems in the valve market

First, some operators have purchased poor quality valves in pursuit of profits and printed famous brand names and certifications, which have caused serious damage to the reputation of qualified valve companies.

Second, refurbishment of the valve, a small number of operators through the re-painted waste valves after the second sale, to the quality of the project to bring serious security risks. When buying a valve, don't be greedy, that is to say, a valve with high quality and low price is understandable but unrealistic. Valve prices due to various reasons, before and after the fluctuations in each period is very large, the purchase of goods than 10 homes can not be exaggerated, it is best to go to the factory inspection and supervision experiments.
