Pneumatic valve purchase information, should pay attention to

pneumatic valve purchase only clear specification, category, work pressure was satisfied with the purchase request, at the time in the market economic environment is not perfect. The pneumatic valve manufacturers produced for commodity competition, each are consistent in pneumatic valve design conception, in different state, formed their own company specifications and commodity characteristics. Therefore in the pneumatic valve to buy more detailed requests skills, get harmony with manufacturer, as a pneumatic valve accessories purchase contract is very necessary.
the pneumatic valve is equipment in the factory to clarify the book shall indicate the following data: pneumatic valve specifications; Type; Pressure of work; Production specification; Pneumatic valve material; Pneumatic valve rod; Sealing materials; Pneumatic valve shaft packing material; Pneumatic valve stem bushing materials; Internal and external anti-corrosion materials; Start operation direction; Revolutions; Work pressure cases open-close torque; Manufactory name; Manufacture date; Factory number; Weight; Connecting flange of the aperture, the number of holes, the base pitch; By graphic method, the control measure of the overall length, width and height; Pneumatic valve flow resistance coefficient; Useful opening and closing times; Pneumatic valve factory inspection related to the protection of data and equipment, matters needing attention, etc.

but expand exports are not professional processing of pneumatic valve to carry out the predicament of a panacea, some problems are inevitable through the seemingly glamorous export data gradually emerge: a lot of pneumatic valve export company for the extension itself export proportion, use domestic market price war strategy, malignant competition aggravating constantly. Many small companies competing for the world order, in the industry and the 'price war'. However, a few small company after obtaining foreign orders in lower commodity prices, in order to reduce costs, often cut corners. The product is unqualified, affect the reputation of the domestic pump pneumatic valve industry. The most terrible is, in the long term domestic pump pneumatic valve industry in the world market is also very suffer may trade barriers. （ A sword)
