A trailer control valve for controlling a hydraulic dual-line brake system of a trailer vehicle has an inlet for a hydraulic supply line of the towing vehicle, a tank outlet for an unpressurized return-flow line of the towing vehicle, a brake pressure outlet, and a supplemental pressure outlet. The brake pressure outlet can be connected in a stepped manner with an electronically controlled brake control valve to the supply pressure inlet or to the tank outlet. The supplemental pressure outlet can connect using a valve arrangement so that an outlet pressure of the supply pressure is reduced to a supplemental pressure at the supply pressure inlet or at the tank outlet. The valve arrangement has a pressure-limiting valve and a shut-off valve arranged in series. The shut-off valve can be a 3/2-way valve, which when not energized, the supplemental pressure outlet is connected to the tank outlet.
