The 040138-169 is an expansion valve for aircraft vapor-cycle air-conditioning systems. This valve meters refrigerant flow into the evaporator while maintaining proper superheat levels and system efficiency. Installed in the liquid line upstream of the evaporator, it modulates flow in response to temperature and pressure changes.
Used in cabin and avionics cooling applications within the environmental control system. Installation and service must follow the aircraft maintenance manual and ECS procedures specific to your airframe.
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.
