The invention concerns a hydraulic valve arrangement ( 1 ) with a working connection arrangement having a first working connection (A) and a second working connection (B), both working connections (A, B) being connectable with a hydraulic consumer ( 2 ), a supply connection arrangement having a pressure connection (P) and a tank connection (T), a first valve arrangement with a first valve ( 12 ), closing the pressure connection (P) or connecting it in a controlled manner with the first working connection (A) or the second working connection (B), a second valve arrangement with a second valve ( 16 ), closing the tank connection (T) or connecting it in a controlled manner with the first working connection (A) or the second working connection (B), and a control arrangement controlling the first valve arrangement and the second valve arrangement. In such a valve arrangement, it is endeavoured to achieve improved operation behaviour. For this purpose, at least with one of the two valves ( 12, 16 ) a working position can be set, in which the first and the second working connections (A, B) are connected with each other.
