The utility model relates to a load sensitive multi-way valve and an engineering machinery hydraulic system. The load sensitive multi-way valve comprises a first unit, a tail unit, one or more reversing units, a head oil inlet, a first oil return opening and a head load feedback oil opening, wherein the reversing units are arranged between the first unit and the tail unit in parallel; each reversing unit comprises a reversing valve, a reversing unit pressure compensation valve and a reversing unit check valve; the reversing unit pressure compensation valve is communicated with the head oil inlet and an oil inlet of the reversing valve; a work oil opening of the reversing valve is communicated with an executing mechanism; an oil return opening of the reversing valve is communicated with a first oil return opening; the reversing unit check valve is communicated with the head load feedback oil opening and a load feedback oil opening of the reversing valve; a first oil way of a spring cavity communicated with the reversing unit pressure compensation valve is also connected with the oil way which communicates the reversing unit check valve with the load feedback oil opening of the reversing valve in a bypassing manner. Due to the adoption of the modular design, the internal oil way is simple, and the expandability is strong.
