Abstract

Control block for controlling a load, especially a hydraulic cylinder, whereby a base block (4) has pressure and return or tank connections. The base block has one or more attached block plates (6, 8) with one or several logic valves (14, 16, 18, 20) and a connection (A) to the load. The logic valves are for connection to one or more pressure chambers of the load.
