Double valve control type load port independent control valve based on mechanical hydraulic pressure difference compensation

The invention relates to the technical field of fluid transmission and control, in particular to a double valve control type load port independent control valve based on mechanical hydraulic pressuredifference compensation. The double valve control type load port independent control valve comprises a secondary overflow valve I, a secondary overflow valve II, a two-position three-way electromagnetic reversing valve I, a two-position three-way electromagnetic reversing valve II, a three-position three-way electromagnetic reversing valve I, a three-position three-way electromagnetic reversing valve II, a shuttle valve, a constant difference pressure reducing valve, a two-position two-way electromagnetic reversing valve and an integrated valve block. According to the double valve control typeload port independent control valve based on mechanical hydraulic pressure difference compensation, the two three-position three-way electromagnetic reversing valves are used for controlling the sameactuator, so that double v
