Valve for regulating a hydraulic driving means, comprising a hydraulic pump (1) which is adapted to the valve for transferring hydraulic fluid through the valve for operating a hydraulic motor (8, 9), the valve being regulated by means of control handles (21a, 22a) for setting the valve in various operating conditions of the driving means. For the purpose of providing a valve having excellent operating properties and compact bulk dimensions, there are, according to the invention, suggested two in the same valve housing (17) arranged valve members (21, 22), which can be operated independently of each other by a respective control handle (21a, resp. 22b), the valve members (21, 22) being arranged rotatable about a common axis in either half of the housing (17). The two valve members (21, 22) can be connected to a common oil pressure chamber (5) which communicates with the hydraulic pump (1), and each valve member (21, 22) is provided with a plurality of corresponding groups of oil channels (A1 to A4, A11 to A14 resp. B1 to B4, B11 to B14), which can be connected to respective hydraulic conduits (10, 11 resp. 12, 13) for operating respective hydraulic motors (8 resp. 9) in various independent rotational directions and with various independent speeds.
