The present invention relates to a relay valve for a pneumatic brake system. The relay valve comprises a housing, a first control pressure port receiving a first control brake pressure for applying, preferably a parking brake, a second control pressure port receiving a second control brake pressure for applying, preferably a service brake. It is noted that, for instance, a parking brake can be applied through the activation of a hand brake valve present in the driver's cabin whereas a service brake is activated via a brake pedal provided in the driver's cabin. Furthermore, in accordance with the present embodiment, the second control brake pressure is configured to be independently applied to that of the first control brake pressure, preferably the first control brake pressure and second control brake pressure are received from at least two independent pressurized fluid sources.
