1. A control device for a central tire inflation system, comprising:
an inlet for connection with a pressure source,
at least a first outlet for connection with a first pneumatic tire,
a supply valve,
at least a first channel valve,
at least a first pressure-limiting valve, and
a vent for venting fluid from the first outlet through the vent,
wherein the supply valve and the first channel valve selectively fluidly connect the inlet to the first outlet and are fluidly connected in series between the inlet and the first outlet,
wherein the first pressure-limiting valve is fluidly connected to the first outlet for limiting a pressure at the first outlet during inflation, and
wherein the first pressure-limiting valve includes a pressure-actuatable actuator fluidly connected to the first outlet and biasing the first pressure-limiting valve towards an open position in which the first pressure-limiting valve fluidly connects the first outlet to the vent via the first pressure-limiting valve.
