The valve includes a housing 2 and a space 7 situated in the housing in which a control element 3 that can be moved by means of a pressure source 1 and with which flow openings 5, 6 for pressure medium connectable to different flow lines are connected, whose size said control element 3 is designed to adjust by means of its movement. At least one opening connectable to a specific flow line is formed from several holes or perforations 6 with small diameter, which are evenly distributed over the inside wall of external space 7 in an area that extends in the direction of motion A of the control element 3 and in the direction perpendicular to this direction. <IMAGE>
