The pile-up valve set for the coal cutter solves the problems that according to an existing small-size electric traction coal cutter product or a low coal seam electric traction coal cutter product, due to the fact that the height of a machine face is low, and the inner space of a box body is small, a system formed by all needed hydraulic elements is hardly assembled in a pump tank according to a conventional valve set. The pile-up valve set for the coal cutter comprises a right guide electromagnetic directional valve, a multi-way block body, a pressure gage I, a low-pressure overflow valve, a filter, a high-pressure overflow valve, a left guide electromagnetic directional valve, a left-hand hydraulically operated directional valve, a right-hand hydraulically operated directional valve, a two-position electromagnetic directional valve and a pressure gage II. The pile-up valve set for the coal cutter has the advantages of being large in number of combined hydraulic elements, compact in structure, small in size, convenient to adjust and maintain, low in cost and the like, and is especially suitable for the hydraulic system of a small-size coal cutter and the hydraulic system of the low coal seam coal cutter. As is proved by the using of the pile-up valve set for the coal cutter under a shaft, the pile-up valve set for the coal cutter is good in operating and convenient to operate and control, meets the using requirements of the coal cutter, and reduces the maintenance cost of a user and producing cost.
