The valve (19,22) comprises two pressure restriction valves for each user point, and a displaceable pressure insert in its end. Feed apertures (M1,M2) work in conjunction with the slide, and are connected via conduits to the opposite sides of the user point (14). An electrically controlled valve (17,20) is connected to the feed conduit pressure side, and feeds pressure medium so that the pressure restriction valve pressure insert is displaced, and fluid flows to the user point to cause it to carry out its required task. |
