Abstract:
An electrohydraulic control valve (1) comprising a control valve element (2) displaceable in a first direction by a pressure in a first pressure chamber (5) and in a second direction by a pressure in a second pressure chamber (6). Each pressure chamber (5, 6) is connected to a line between a high pressure port (PP) and a low pressure port (PT) via a magnetic valve (11, 12). Each magnetic valve (11, 12) is a three-way valve and comprises a first valve seat (17) and a second valve seat (18). A space (19) between the first valve seat (17) and the second valve seat (18) is connected to the pressure chamber (5, 6) and a first valve element (20) positioned outside the space (19) cooperates with the first valve seat (17) and a second valve element (21) positioned outside the space (19) cooperates with the second valve seat (18).
