The 0850451-2 is a heat control valve for aircraft environmental systems that regulates heated airflow from exhaust-shroud or bleed-air heat sources to cabin and defrost outlets. Mounted on the firewall, this valve modulates airflow temperature by controlling the proportion of heated air entering the cabin heating and defrost circuits. Installation follows aircraft maintenance manual specifications and FAA AC 43.13-1B guidance.

Verify compatibility with your aircraft's Illustrated Parts Catalog before return to service.
