VALVE ASSEMBLY (P/N 50-554341-2) - As Removed

The 50-554341-2 is a right-hand bypass valve assembly for Beechcraft King Air 90/100/200 series aircraft. This component regulates airflow within the environmental control system (ATA 21) to maintain cabin temperature. It mixes cooled heat-exchanger air with bleed air, directing the combined flow to achieve target cabin conditions.

Installed in the environmental ducting, the valve responds to temperature demand signals and modulates bypass airflow accordingly. Verify compatibility with your aircraft's Illustrated Parts Catalog before installation and follow the applicable maintenance manual procedures.
