<p>In a hydraulically operable distributing valve, the control piston of which is controlled by electrically operable pre-control valves of small rated widths integrated into the distributing valve housing as built-in units in which the hydraulic connection between the pre-control valves and the distributing valve is via channels running in the distributing valve housing, the channels in the distributing valve housing, especially for large series production, take the form of cast-in channels and the connections of the pre-control valves are suited to the size and arrangement of said channels.</p>
