Product Description
The 390-384025-0003 is a secondary outflow valve for aircraft cabin pressurization systems. This redundant valve regulates overboard airflow discharge to maintain cabin altitude within safe operating limits as part of the Environmental Control System (ATA 21). Positioned near the aft pressure bulkhead, it modulates flow alongside the primary outflow valve to prevent over-pressurization and ensure cabin safety.
Installation requires compliance with aircraft AMM procedures and IPC compatibility verification before integration into the pressurization system.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
