for the simultaneous actuation of valves, electro hydraulic, hydraulic consumer devices (5),(6) are connected through valves 3 / 2 (13, 16) under pump pressure (2) or in the return duct (4).these valves may be connected to a pipe (3) by the pressure control valves (19, 22) to pre order form a magnet absorption power are not subject to pressio 50 milliampselectrohydraulic valves. through several channels (25, 26) are connected to the valves for preorder leads control pressure (3), and at the same time, locked hydraulically.
