A pressure control valve (1) designed as a closed-end pressure regulator is proposed, which comprises two valve seats (7, 11) arranged in a hydraulic half-bridge circuit, with an electromagnet (2) having a magnetic core, a magnetic coil (3), and a displaceable armature (4), with an anchor rod (5) displaceable by the armature (4) for a closing part (6), which can be made to strike against a first valve seat (7) of the tank edge, and with a push rod (9), which is connected to the anchor rod (5) or is designed as a single piece with the anchor rod (5), which can move a locking element (10) designed as a ball out of a ball seat (11) of the inlet control edge, in which the push rod (9) is configured in such a way at its end facing the ball seat (11) that the opening cross-section of the inlet control edge (12), that is, the ball seat (11), can be modified depending on the axial position of the push rod (9) in such a way that the cross-section is reduced when the target pressure is low, in order to reduce the inlet volume flow, while the total cross-section of the inlet edge (12) is made available when the target pressure is high and/or in which the valve seat (11) is designed in such a way that its diameter on the side facing the ball (10) is smaller than the diameter on the side facing away from the ball (10).
