[origin: WO03074883A1] Disclosed is a valve arrangement for triggering consumers (4) in a manner that is independent from the load pressure, comprising a main valve (10) which is provided with a directional part and a metering cover part. The valve arrangement comprises a check valve (18) for sealing in a leakage-free manner a working pipe which leads to the consumer. Said check valve (18) is provided with a pilot valve (20) via which a pressure chamber of the check valve (18), which acts in the closing direction thereof, can be relieved towards a tank or a low-pressure source. The pilot valve (20) is controlled by a main slider (12) of the main valve (10).
