A pressure balanced 2/2-control flow pressure regulating seat valve (42) is provided in a control line (43). Other control lines (33, 34) are attached to inputs of the switching valve and selectively impinged with control pressures (Pst1, Pst2) from a control pressure supply (20) for electrohydraulic proportional servo controls (24, 25) of a three-position directional control valve (W).",
