With the implementation of national standard GB25974-3-2010, current hydraulic valve production enterprises do not have the ability to test all the ex factory projects. In view of this phenomenon, a valve factory inspection device for hydraulic support was developed. The device has the advantages of convenient operation, good performance, completed functions etc. The factory inspection ability and level of enterprise are greatly enhanced, the product quality of hydraulic support valve is ensured, the coal mine hidden safety trouble is reduced.
