But this high-speed oscillation valve industry will bring tremendous opportunities butterfly model, the results shocks will make more rational operation of the market. Localization of the road end of the valve abnormality "bumpy." The base member has become a constraining the development of China's high-end manufacturing to the short board, the government will continue to increase during the second five high-end equipment, parts localization efforts. Here we select the "embodiment" in reference to the development of several key industry representative valves import substitution feasibility analysis. From the analysis, we can see that the various sub-sectors of the feasibility of import substitution vary greatly valve flange butterfly valve needs to end more policy guidance and research support. Ventilation butterfly valve industry in the national economy, as an important part of the equipment manufacturing industry butterfly, play a very important role. Because China's domestic valve manufacturing level compared with the international advanced level there is still a gap, a lot of high-parameter, high temperature and high pressure, high level of critical valves former pound has been dependent on imports, such as the European OMAL brand has been the main choice of target domestic industry valve applications .
