The inventions relates to a suspension control valve arrangement for a pneumatic suspension system of a commercial vehicle,said suspension control valve arrangement comprising:a supply port to be connected to a supply pressure,a delivery port to be connected to a suspension bellows of the commercial vehicle,an exhaust port for exhausting air,a housing (2), in which said ports are provided,a service valve means provided between said ports and switchable into different valve positions,an operation control means (5, 6) for switching said service valve means into one of the following normal operation modes of a normal operation status:a blocking position for a blocking mode for blocking an air supply from said supply port to said delivery port,a supply position for a supply mode for supplying air from said supply port to said delivery port oran exhaust position for a normal exhaust mode for connecting said delivery port to said exhaust port via said service valve means.In order to realise a suspension control valve arrangement which can be made with little effort and high reliability a dump-control device (7, 11) is provided in said housing (2) for switching between said normal operation status enabling said normal operation modes and a quick-dump mode (IV), wherein in said quick-dump mode (IV) said delivery port is connected to said exhaust port by bypassing said service valve means.
