The WBF pressure reducing proportional pilot control valve is the hydraulic control components witch is development for the full-hydraulic excavators in Domestic. It has to manipulate light to control sensitive, reliable, easy to install maintenance, etc., and has a good proportion of control characteristics and secondary

characteristics decompression, It has a variety of output pressure range for host of different operating conditions require. It has the human nature handle, with 1-4 electronic control s. At the same time, it is suitable for large and medium engineering machinery such as cranes, etc. in the hydraulic valve to control the pilot proportion.
