Pneumatic control valve in a broad range of industries in the universal application, it can automatic control valve control function is its biggest advantage, in the years of development, especially in recent years, the economic science and technology rapid development at the same time, control valve also got great progress, but it also increased in market competition. There is no denying the fact that China's valve manufacturer is numerous, has its advantages and disadvantages exist. As the saying goes, many hands make light work, can create more wealth, from our country is the world's largest producer of valve can see its manufacturer many advantages: much and miscellaneous, can be accomplished without norms or standards, manufacturer many cause confusion of market, the competition is not reasonable, and this is where its defects. Regulating valve should seek squeezed break out, control valve is now in petroleum, chemical, biological and cuhk engineering, should notice to high specification the direction of development, and strengthening technical improvement and innovation, development of new products, and other valve manufacturer or valve design institute strengthen exchanges, in order to realize the sustainable development.
