Product Description
The 4180-00-74 ECH is an outflow valve assembly for Beechcraft Duke pressurization systems. This metal-bodied component regulates cabin pressure by modulating discharge airflow from the pressurized cabin. Installed in the cabin pressurization system to exhaust excess air and maintain target cabin altitude, the valve responds to pressure differential signals.
Installation requires verification against the aircraft Illustrated Parts Catalog and adherence to maintenance manual procedures. Perform leak and function checks before returning the aircraft to service.
