A relay valve module of a pneumatic brake system for a vehicle includes a relay valve and an actuating unit. A valve body of the relay valve defines therein an air supply chamber in fluid communication with a supply air reservoir, and a delivery chamber in fluid communication with brake cylinders. A valve seat is disposed between the air supply and delivery chambers; and is opened and closed by movement of a valve member that is actuated by a piston slidable relative to the valve body. The actuating unit includes a stem assembly moved by a pressure to press the piston so as to move the valve member, and an actuating assembly electrically connected with an electronic control unit of the vehicle to receive a brake signal therefrom to provide the pressure to the stem assembly.
