A proportional pressure control valve ( 1 ) for controlling the pressure level in a hydraulic circuit having a push rod ( 5 ) as a connection between a control element ( 13 ) arranged in the hydraulic circuit and a proportional magnet located in a housing ( 10 ), which comprises a magnetic core ( 2 ), a magnetic anchor ( 3 ), and a magnetic coil ( 4 ), the magnetic coil ( 4 ) and the magnetic core ( 2 ) are securely connected to the housing ( 10 ), and the magnetic anchor ( 3 ) can be moved axially back and forth between two end positions by means of a magnetic force. At least one part of the magnetic anchor ( 3, 3'' ) is arranged so as to be movable relative to the anchor rod ( 6 ) in dependence upon the magnetic flow, so that in this way either the gaps ( 11, 14 ) are enlarged and/or an additional second gap ( 8 ) is produced.
