The invention relates to a hydraulic valve arrangement for supplying a pressure medium to a hydraulic load, having two working connections for connecting to the load. The valve arrangement comprises a first inlet flow measuring diaphragm, via which a first inlet flow can be routed towards the load from the first of the working connections, and a second return flow measuring diaphragm, which is separate from the first inlet flow measuring diaphragm and via which a first return flow can be routed from the load via the second working connection. The valve arrangement also comprises a second inlet flow measuring diaphragm, via which a second inlet flow can be routed towards the load from the second of the working connections, and a first return flow measuring diaphragm, which is separate from the second inlet flow measuring diaphragm and via which a second return flow can be routed from the load via the first working connection. The invention further relates to a hydraulic valve block comprising at least one such valve arrangement and to a hydraulic drive comprising a hydraulic pump, at least one hydraulic load, and at least one such valve arrangement or valve block. |
