Abstract (en)
[origin: EP1205669A1] The valve block is fitted between a path valve and a hydraulic user unit, taking over a load-holding function, where the user unit can be a tilt cylinder in a forklift truck. It incorporates at least two stop valves (6,7), which have a valve closure member (26,27), which works in conjunction with a valve seat (28,29) and in a stop position separates a user side (A,B) from a supply side (C,D). By means of at least one spring (61,62) in a spring chamber (4,5) it is loaded in the stop direction. The spring chamber of each of the stop valves is connected with a pre-control valve (10), which is a releasable check valve.
