An electromagnetically actuated pressure control valve (10) is proposed which controls a pressure as a function of the size of an input signal on a proportional magnet (11). The pressure control valve (10) comprises in a common housing (14) a pilot valve (12) and a main control valve (13) whose beaker-shaped hollow gate (22) controls the connections between three ports (19, 21, 26), of which the consumer port (26) for controlled pressure faces the open end (25) of the hollow gate (22) and the spring (27) which loads the hollow gate (22). In this way, a pressure control valve (10) of compact construction is achieved, which can control the pressure down to almost zero, in particular in electrohydraulic controls of injection moulding machinery. <IMAGE> |
