Hydraulic Power Units Pressure Reducing Valve

The QBF decompression proportional pilot valve is the hydraulic control device for the domestic development to all series of hydraulic cranes, the valve with small volume, can take more electrical control (up to 8), control light, control of sensitive, reliable and convenient installation and maintenance advantages, and has the proportion of good control characteristics, with decompression with two characteristics, different requirements for the host. It also applies to all kinds of medium and large construction machinery hydraulic proportional control.
