PURPOSE:To reduce a mounting space, by connecting respective valve blocks having relations with a plurality of hydraulic cylinders with each other and intensifying them into at least one block, in the titled hydraulic circuit to be adopted to a device cutting off metallic scrap by compression. CONSTITUTION:A compression cutting-off device for reclamation of metallic scrap possesses respective hydraulic cylinders 1-5 for lateral pushing, feeding, opening and closing of a lid, cutting-off and compression, with which valve blocks 10-40 for driving of cylinders are connected. In addition to the above, a decompression valve block 60 is connected with the compression valve block 50. In this instance, the respective valve blocks 10-30 for the lateral pushing, the feeding and the opening and closing of the lid are made into a block A by connecting them in series with each other and similarly the respective blocks 60-40 for the decompression, compression and the cutting-off are made into a block B. Then inlet ports of the valve blocks 10, 60 each are connected with a hydraulic pump 7 and outlet ports of them are connected with a hydraulic tank 6.
