Current valve enterprises technological innovation capacity is insufficient, which is a stumbling block for the development of our valve industry. At present, many of the domestic valve companies to introduce advanced technology rarely re innovation. When overseas customers visit China's heavy industry projects, such as electricity, petrochemical, and found a lot of projects in the valve products only in the design of the prototype of the west to do a change. China's valve industry is not high, the domestic backbone enterprises have a certain R & D conditions, and most of the valve enterprise R & D Center personnel, facilities, lack of adequate funding, R & D and technical services are more closed, mainly based on business services, according to the sales orders and design, process preparation, functions are relatively simple; such as the valve production process, or a small amount of new product development.

Domestic valve design level compared with the developed countries, there is a big gap. Process are more backward, although some domestic valve manufacturer with modern equipment, automatic operation can be achieved, and even make western enterprises to shame. A lot of Valve Companies in the foundry equipment is poor, in the casting steel, iron, aluminum, copper, composite materials, etc., but the valve products, but due to the backward casting process, cast steel, cast iron and other raw materials in the production process a lot of waste, environmental protection is poor.

Now most of the valve manufacturers are not able to independently conduct effective analysis of the valve, and these manufacturers are required to design the seismic analysis, only individual manufacturers more complete control of the valve's stress calculation and seismic analysis, valve fatigue analysis, and impact analysis, to a certain extent, the domestic manufacturers to improve the level of R & D capabilities. Domestic research cooperation is also lower, the product technology development of independent development, and some colleges and universities and research institutes have professional, office, but only the role of the valve, the requirements of the characteristics of technical requirements, do not expand the valve product design and manufacturing technology research and development, even if there are design drawings, often lack of technology, and some of the key due to lack of practical verification means, which is the main cause of the overall technical level of domestic valve.

High technology level of the valve companies are usually equipped with specialized R & D center, compared to their strong financial, all kinds of relevant research institutions and professional excellent technical engineers, and these R & D centers are often based on the need to have specialized laboratories and testing organizations, and the application of the valve products are also very complete: can be used to analyze the advanced performance of new products and new technologies.

A lot of enterprise valve products, although many national patents, but a lot of patents only for practical patents, technical content is not high, a lot of patents only on the structure of some improvements, no substantial improvements in the invention. Some of the existence of imitation and plagiarism, because many valve users for many years to stay in the use of traditional products, and many of the products inside and outside the structure for many years no substantial improvement and improvement.

Actually in terms of technical level, the conventional valve design and material application, we compared with foreign famous enterprises, and no much difference, in the manufacturing process there is no unbridgeable gap, and that difference in what place? But according to the actual situation is poor in serious word, there is such a product, originally is a German company's valve patented products, there are several different companies at the same time the production, one is a foreign company, one is a Taiwan funded enterprises, one is domestic companies. The same product map, produced by the valve in kind but different. The former two companies internal quality, appearance is better than the domestic do. It is puzzling that: these companies are in China's domestic production of such products, and the casting billet are from domestic factories, but the results vary widely. In a sense, our business philosophy, the pursuit of goals and foreign enterprises have a big gap, especially in the product processing process, there is a certain problem, but also our reflection.

The practice of foreign companies with Chinese enterprises are different, China's valve business to engage in infrastructure, expansion of production plants, production equipment, plant is also an expansion, the pursuit of large and modern style, and just want to expand the production scale, ignoring the new product development and investment, product potential serious shortage, and the production of products are generic, and too much energy into the market, the use of improper means to engage in product sales, and thus lack of core competitiveness. A lot of domestic enterprises in the development of the more, the reference to the design of other manufacturers, thereby ignoring the importance of the original experimental data, so that the development of the product only has a shape and no real soul.

Valve as a whole industrial system has some problems, our research and development system is very weak, but the weak innovation capacity, and now some companies have many factories
