Integrated valves of variable preferential flow leveling

The utility model provides an integrated valves of variable preferential flow leveling, integrated valves of variable preferential flow leveling includes: overflow valve 1, energy -conserving the 2, the 1st magenetic exchange valve 3 on the valve of pressure compensation, the 2nd magenetic exchange valve 5, A1 mouth flow control valve, A2 mouth flow control valve, B1 mouth flow control valve, B2 mouth flow control valve, M pressure -measuring opening, P oil inlet, T oil return opening, C oil -out, first shuttle valve 11, second shuttle valve 8 and third shuttle valve 4. The utility model discloses integrated valves of variable preferential flow leveling can realize that the upper and lower speed of leveling cylinder is unanimous, can adjust the operating speed of leveling according to different work condition, and the leveling effect is steady, this integrated valves of variable preferential flow leveling still has energy -conservation, the efficient advantage of leveling, this valves integrated level is high, effectively saves the fluid pressure line, and convenient scene is installed and is maintained.
