Valve device for a roof lining system for motor vehicles, the valve device being designed for controlling at least two air flows to be emitted to a motor vehicle interior via the roof lining system, and wherein: - the valve device has a first air duct, a second air duct, a first flow actuator (130, 130') arranged in the first air duct and a second flow actuator arranged in the second air duct; - said first flow actuator (130, 130') is drivable in a first direction of rotation and in a second direction of rotation and is rotatable about an axis of the first flow actuator (130, 130') between an open position, in which flow through the first air duct is enabled, and a closed position, in which the first flow actuator (130, 130') prevents flow through the first air duct; - said second flow actuator is rotatable with respect to said first flow actuator (130, 130') and is rotatable about said axis between an open position, in which flow through said second air duct is allowed, and a closed position, in which said second flow actuator prevents flow through said second air duct; and - the second flow actuator is drivable by means of the first flow actuator (130, 130') in the first direction of rotation and/or in the second direction of rotation, the valve device being characterized by the following features: - the first flow actuator (130, 130') has a first tappet and a second tappet which are angularly spaced apart with respect to the axis; - the second flow actuator has an end stop with a first end stop surface and a second end stop surface opposite thereto; - the first tappet is contactable with the first end stop surface, so that upon rotation of the first flow actuator (130, 130') in the first direction of rotation, the second flow actuator is driven in the first direction of rotation by means of the first flow actuator (130, 130'); and - the second tappet is contactable with the second end stop surface, so that upon rotation of the first flow actuator (130, 130') in the second direction of rotation the second flow actuator is driven in the second direction of rotation by means of the first flow actuator (130, 130'). - the valve device has a first air duct, a second air duct, a first flow actuator (130, 130') arranged in the first air duct and a second flow actuator arranged in the second air duct; - said first flow actuator (130, 130') is drivable in a first direction of rotation and in a second direction of rotation and is rotatable about an axis of the first flow actuator (130, 130') between an open position, in which flow through the first air duct is enabled, and a closed position, in which the first flow actuator (130, 130') prevents flow through the first air duct; - said second flow actuator is rotatable with respect to said first flow actuator (130, 130') and is rotatable about said axis between an open position, in which flow through said second air duct is allowed, and a closed position, in which said second flow actuator prevents flow through said second air duct; and - the second flow actuator is drivable by means of the first flow actuator (130, 130') in the first direction of rotation and/or in the second direction of rotation, - the first flow actuator (130, 130') has a first tappet and a second tappet which are angularly spaced apart with respect to the axis; - the second flow actuator has an end stop with a first end stop surface and a second end stop surface opposite thereto; - the first tappet is contactable with the first end stop surface, so that upon rotation of the first flow actuator (130, 130') in the first direction of rotation, the second flow actuator is driven in the first direction of rotation by means of the first flow actuator (130, 130'); and - the second tappet is contactable with the second end stop surface, so that upon rotation of the first flow actuator (130, 130') in the second direction of rotation the second flow actuator is driven in the second direction of rotation by means of the first flow actuator (130, 130').
