The disclosure relates to a hydraulic control valve for controlling hydraulic circuits, which comprises a valve housing defining a valve bore; a first spool valve slidably positioned within the valvebore and adapted to control a first hydraulic circuit; and a second spool valve slidably positioned within the valve bore and adapted to control a second hydraulic circuit. The first spool valve and the second spool valve are positioned co-axially within the valve bore and are independently slidable within the valve bore to allow the first and second spool valves to control the first and second hydraulic valves independently of one another. 本公开涉及一种用于控制液压回路的液压控制阀，包括：阀壳体，限定阀孔；第一滑阀，可滑动地位于所述阀孔内并适于控制第一液压回路；以及第二滑阀，可滑动地位于所述阀孔内并适于控制第二液压回路。所述第一滑阀和所述第二滑阀同轴位于所述阀孔内并且可独立地在所述阀孔内滑动，以允许第一和第二滑阀彼此独立地控制第一和第二液压阀。
