A valve device including an outlet port, a first valve unit with a first valve element for setting a first throttle opening for influencing a first airflow of pressurised air which is to be output at the outlet port or is to be released via the outlet port, a first throttle control loop for the closed-loop control of the first throttle opening according to a first setpoint, a pressure control loop for the closed-loop pressure control of an outlet pressure present at the outlet port to a pressure setpoint amid the use of a first throttle control loop as a subordinate control loop, wherein on closed-loop pressure control the pressure control loop specifies a first throttle setpoint to the first throttle control loop as the first setpoint, wherein the valve device is further configured to provide a throttle setting function and, within the throttle setting function, to limit the first throttle opening to a first limitation value and/or within the throttle setting function to specify a first direct setpoint which does not come from the closed-loop pressure control, to the first throttle control loop as the first setpoint.
