So, the valve will obtain rapid development. Globe valves are using the globe valve seat disc along the center of the channel, to control the movement of a pipeline open circuit valve. Can be used in the system of medium flow. At present, has been widely used in petrochemical industry, electric power, metallurgy, chemical and urban construction. Based on the development of DN40 cut-off valve, the purpose, structure, features of certain of this, enhance the understanding of the body. According to the analysis of the valve, the production type, type and manufacturing methods, blank processing route, worked out the unreasonable processing route, and the reasonable processing, using the correct processing manufacturing qualified quality valves.
