Abstract: A standard hydraulic control valve block has a first control valve (2) and a second control valve (3) that co-operates with the first control valve and communicates therewith through hydraulic medium lines (28-31, 33). The second control valve (3) has a valve piston (5) controlled on the one hand by a hydraulic control pressure in a pressure chamber (25) and on the other hand by a spring pressure part (7). In order to simplify the construction and mounting of the control valve block without affecting its operation and using a remote controlled seat valve, an additional hydraulic medium line (36) is designed in the control valve block and the spring pressure part (7) of the second control valve (3) is replaced by an electrically controlled seat valve (60.1; 60.2). The seat valve (60.1; 60.2) has an electromechanical control part (66.1; 66.2) and at least two hydraulic connections (63.1; 64.1) that act as a valve inlet (63) and a valve outlet (64.1; 64.2). The valve piston (5) of the second control valve (3) is at rest so that one (64.1; 64.2) of both hydraulic connections (63, 64.1; 64.2) of the seat valve (60.1; 60.2) is at the same time connected to an available hydraulic connection (T) and the other hydraulic connection (63) is connected to the additional hydraulic medium line (36).
