High-end valve development bottleneck analysis

With the recovery of the world economy, the import and export of China's valve products have also increased, but due to the large differences between technology and foreign countries, in the future development, we must overcome this bottleneck.

Nowadays, with the great development of China's economy and science and technology, the variety of valves is also increasing. The industries that apply valves are also increasing. The petrochemical industry, the oil refining industry, the nuclear power industry, and the thermal power industry are all widely used. And more and more industrial applications also have more new requirements for valves, and the quality and technical requirements for valves are also getting higher and higher. In addition, valves are required for the construction industry as well as for special industries. The use of the valve is very extensive, and it is used in many companies. This fully shows that the valve is developing very quickly and has a good prospect.

In the continuing favorable macroeconomic situation, most of the valve industry's production and sales indicators have maintained rapid growth, but due to the impact of price wars, industry sales revenue and profits have dropped significantly compared with last year. In general, however, the industrial concentration of China's pump and valve market is relatively low, and the production of medium and low-end products is the mainstay. In terms of owning core technologies, there is still a certain gap between domestic enterprises and developed countries in the world.

At present, only the low-pressure valves in the domestic valve market have reached the international market's acceptable level. High-pressure valves still need to be imported from abroad, especially some key projects, such as the West-East Gas Pipeline Project, the main line requires a large number of valves. The main reason is that the equipment and technology are backward and the degree of specialization is low. Especially in some high-end technologies, there is still a big gap between domestic products. With the opening up of foreign investment policies, leading foreign valve companies have entered China, their market share has continued to expand, and products have also been integrated into various fields.

Many high-quality valves are developed and produced by foreign companies. Although the domestic valve production backbone enterprises have been able to design and manufacture various valves according to ISO international standards, DIN German standards, AWWA American standards and other international standards, some manufacturers' products have reached the international advanced level. However, the quality is still not stable enough, such as running, running, 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. However, domestic companies are facing increasingly severe competition, and new product development technologies cannot compete with them, leading to the reduction of consumer spending on domestic brands and the purchase of foreign brands. It can be seen that the level of new product technology research and development has greatly affected the demand for domestic and foreign investment products.

China's valve industry still has some problems, such as China's valve companies mainly in low-level, small-scale, family workshop-based enterprises. In terms of products, due to repeated investment and inadequate technology introduction, the leading products of China's valve companies are still low-quality mass products. It is understood that currently all kinds of valves produced by Chinese enterprises have the drawbacks of external leakage, internal leakage, poor appearance quality, short life span, inflexible operation, and unreliable valve electric devices and pneumatic devices. Some products are only equivalent to the last century. At the international level in the early 1980s, some of the valves needed for high temperature and high pressure and critical equipment still depended on imports.

China's valve industry in the industrial structure, the industrial chain of industrial valves, as well as the industry's degree of specialization and foreign companies have a large gap between the quality of domestic valve products caused by the low: due to the rapid expansion of the market, the original state-owned valve companies have Shut down and switch. According to the market survey, although a group of township enterprises developed rapidly, due to the low starting point of the township enterprises, the technical strength is very weak, and the equipment is simple, most of the products are imitating production, especially the low-pressure valves for water supply and drainage problems are serious, but the above problems and Does not affect the broad prospects of China's valve industry in the future. This is mainly due to the support of national policies and the strong demand for valve product markets. In particular, several projects of the “West-to-East Gas Transmission”, “West-to-East Electricity Transmission”, and “South-to-North Water Transfer” projects require a large number of valve products to be started. .
