Abstract (en)
[origin: EP1369596A2] Hydraulic valve arrangement (1) comprises a supply connection arrangement having a high pressure connection (P) and a low pressure connection, a working connection arrangement having two working connections (A, B), a control valve (3) arranged between the supply connection arrangement and the working connection arrangement, and a shut-off valve (24, 28) for each working connection which is arranged between the control valve and the working connection and has a valve element (25, 29) that is mechanically controlled with the aid of a tappet (36). The tappet ends on its side facing away from the valve element in a pressurized pressure chamber. Preferred Features: The pressure chamber of the tappet for one shut-off valve is defined by the valve element of the other shut-off valve. Both shut-off valves are provided with a common tappet. The tappet is shorter than the distance between the valve elements of the two shut-off valves.
