Abstract
A hydraulic valve device includes a fluid connection arrangement (10) having different connections and a mobile control (18) for at least partially controlling connections of the fluid connection arrangement (10). The control (18) is provided with load reporting and load detecting connections (32, 38; 34, 36). According to the displacement position of the control (18), at least one part of the connections of the fluid connection arrangement (10) are interconnected in a fluid-guiding manner. The control can then be brought with precision into the required functional positions, with a favorable dynamic driving behavior.
