Product Description
The 45AS48004-003 is a flapper valve that functions as a one-way check element in aircraft pneumatic ducting. This valve prevents reverse airflow in environmental control system air ducts, maintaining directional flow during normal operations. The flapper mechanism opens to allow forward airflow and closes to block backflow, protecting downstream components from pressure reversals.
Commonly installed in Hawker 400XP environmental systems. Installation and testing must follow the aircraft maintenance manual and verify compatibility with your aircraft's Illustrated Parts Catalog.
