The invention relates to a trailer control valve comprising a storage pressure inlet (P), a tank outlet (T), a brake pressure outlet (C), and a supplemental pressure outlet (S). The brake pressure outlet can be connected to the storage pressure inlet or the tank outlet in a stepped manner by means of an electronically controllable brake control valve (34), and the supplemental pressure outlet can be connected either to the storage pressure inlet, thereby lowering the outlet pressure of the storage pressure to a supplemental pressure, or to the tank outlet via a valve assembly (39) comprising at least one electronically controllable valve (38). The valve assembly (39) has a pressure-limiting valve (36) and a shut-off valve (38), wherein the pressure-limiting valve and the shut-off valve are arranged one behind the other in series, and the shut-off valve is fluidically connected downstream or upstream of the pressure-limiting valve. The outlet pressure of the valve assembly can be reduced to the supplemental pressure by means of the pressure-limiting valve, and the shut-off valve is designed in the form of a 3/2-way solenoid switching valve, via which the supplemental pressure outlet is connected to the tank outlet in a non-energized state and to the work outlet of the pressure-limiting valve in an energized state.
