Abstract (en)
[origin: WO2010108570A1] The invention relates to a hydraulic valve device having a fluid connection arrangement (10) and having a displaceable control device (16) for at least partially actuating connections of the fluid connection arrangement (10), wherein the control device (16) can be actuated by two opposing pilot valves and is held in the neutral position thereof by centering springs. By providing at least one throttle position (da1, db1) between each pilot valve and the control device that can be connected for fluid flow between a load probe connection (LFA) and a load indicating connection (LMA) or a load probe connection (LFB), a hydraulic valve device enables fine control for moving loads.
