Product Description
The 99643-61150 is a pneumatically-actuated engine air shut-off valve that isolates airflow in nacelle and bleed-air ducting systems. This valve enables rapid engine air isolation during maintenance procedures, fire emergencies, or anti-ice circuit control. Installed in engine compartment ducting, it responds to pneumatic pressure signals to open or close the air passage reliably.
Stainless steel construction resists corrosion in high-temperature engine bay environments. Installation follows aircraft maintenance manual specifications and requires compatibility verification with your aircraft's Illustrated Parts Catalog.
