Abstract
The invention concerns a hydraulic valve arrangement () with at least two valve modules (-), each having a supply channel arrangement with a high-pressure channel () and a low-pressure channel (), a working connection arrangement with at least one working connection (A, B), one directional valve arrangement () between the supply channel arrangement () and the working connection arrangement (A, B) and a compensation arrangement (), which is acted upon by a pressure in a load-sensing arrangement. It is endeavored to increase the number of control possibilities. For this purpose, the load-sensing arrangement of at least one valve module (-) has a pressure influencing arrangement (-) that differs from a pressure influencing arrangement (-) of a load sensing arrangement of another valve module (-).
