Product Description
The 34-305 is a thermostatic expansion valve for aircraft vapor-cycle air conditioning systems. This valve meters refrigerant flow into the evaporator while regulating superheat to protect the compressor from liquid return. A sensing bulb monitors evaporator outlet temperature and automatically adjusts valve opening to maintain optimal cooling performance.
Installed at the evaporator inlet, the 34-305 controls refrigerant distribution across varying flight conditions and cabin loads. Replacement requires system evacuation and recharging per aircraft maintenance manual procedures. Verify compatibility with your aircraft's Illustrated Parts Catalog before installation.
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.
