1. A control unit for electrohydraulic actuation of motor vehicle clutches, comprising:
a main housing, and
at least one valve unit configured to be inserted into the main housing, the at least one valve unit having:
a metal valve housing configured for receiving an electrically actuated valve,
a plug housing fastened to the metal valve housing and formed from a plastic material, and
a first electrical contact disposed in the plug housing and configured to be electrically connected to the electrically actuated valve, and
a clamping electrical contact, configured for electrically connecting the first electrical contact of the at least one valve unit to an actuating electronics system configured for operating the electrically actuated valve, connected to the main housing, and
the plug housing forms a dielectric resistance between the clamping electrical contact and the metal valve housing, the plug housing extending at least over an entire projection surface of the clamping electrical contact onto the metal valve housing along a surface of the main housing normal to an outer side of the metal valve housing.
