Abstract:
A system for waste system pressure management is disclosed. In one or more embodiments, the system includes an electronically controlled valve and a controller communicatively coupled to the electronically controlled valve. The electronically controlled valve is coupled to a suction path of an aircraft waste system. The controller is configured to determine a pressure differential between an aircraft cabin and a vacuum source for the suction path. The controller is further configured to generate one or more signals to actuate the electronically controlled valve from a first position to a second position to regulate a pressure in the suction path when the pressure differential between the aircraft cabin and the vacuum source exceeds a threshold pressure differential. In embodiments, the electronically controlled valve is configured to allow more airflow through the electronically controlled valve in the second position than in the first position.
