A valve providing a controlled pressure for a hydraulic device includes a first control element and with a second control element, the first and second control elements being movable relative to one another under the influence of a nominal value input at a steering device and being brought into a neutral position with respect to one another by means of a restoring element, and a driving device with which the control elements can be moved relative to one another independently of the nominal value input at the steering device, in order to shift the hydraulic center of the valve. In order to create a valve with small overall dimensions and simple and reliable functions, provisions are made pursuant so that the driving device is constructed as an electrodynamic driving mechanism formed coaxially with the valve, and/or with an electrostatic stepper motor.
