A directional control valve including a force-regulated magnet, a control piston, an actuating piston, first and second elastic elements and a conductor. The control piston is displaceable using the force-regulated magnet, the control piston varies the flow cross-section between pressure, piston, and tank connections. The actuation piston has a first and second chamber. The first elastic element acts against a hydraulic pressure in the first chamber. The actuating piston being connected to the control piston by the first elastic element. The second elastic element acts against the hydraulic pressure in the first chamber. The actuating piston being connected by the second elastic element to the control housing or the flange. The conductor is connected to the electromagnet for control of the electromagnet such that the magnetic force and the position of the control, the actuating, and the pilot pistons are regulated by a voltage generated in the conductor.
