Product Description
The 321456-2 is an electrically actuated bleed air shutoff valve that isolates high-temperature bleed air in aircraft environmental control systems. This valve provides on/off flow control during engine start, shutdown, and fault conditions, preventing unwanted air supply to cabin pressurization and heating circuits. Installed in the bleed air distribution manifold, it responds to electrical commands from the aircraft control system.
Installation requires verification against the aircraft maintenance manual, IPC compatibility check, and proper wiring and pneumatic schematic routing per OEM specifications.
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.
