Development of intelligent hydraulic components in mountain and river  

Recently, the test valve was successfully completed on the 36T excavator by the medium excavated valve developed by the mountain and the river. It is understood that the industrial test of the independent multi-channel valve of the 36T excavator will be completed in order to achieve the goal of the homemade matching of the product as soon as possible.

Sunward R & D dug in multi valve not only has the advantages of novel structure design, the positive and negative flow control models shared universal range coverage, and the design of hydraulic circuit in multi valve on the bucket rod adduction full regeneration control, boom down main pump oil supply control, priority control and other compound action than cases of patent, so that the main valve is operating speed, good energy-saving effect, good coordination.

This is a breakthrough after the completion of the 21T excavator test in 2014. The commissioning and actual digging test lasted for more than two months. The test results showed that the self excavating multi-channel valve developed by Shan He intelligence fully met the function and performance requirements of 36T excavator, and compared with imported similar products, the operation efficiency and fuel consumption achieved good results. Sunhe intelligent has already had the ability to excavate multiple valves in independent research and design, manufacturing and testing, which indicates that Shan He intelligent has achieved some achievements in the field of hydraulic components development.
