A parking brake valve device for controlling a storage spring parking brake in an electropneumatic brake system includes a compressed air input configured to be connected to a compressed air supply, a parking brake output configured to control a storage spring parking brake, and a trailer-control control output configured to control a trailer control valve (TCV) for a trailer brake system. The parking brake valve device further includes a relay valve pilot control region and a relay valve, a TCV pilot control region configured to control the trailer-control control output, an inlet valve configured to be controlled with a first electrical control signal for supplying air to the TCV pilot control region and the relay valve pilot control region, and a connecting valve configured to be controlled by a second control signal to connect and disconnect the TCV pilot control region and the relay valve pilot control region.
