Expansion Valves – Replacement Car Air Conditioning Components

Shop replacement automotive air-conditioning expansion valves at Shop4AllParts. Explore vehicle-specific A/C expansion valves for compatible cars, SUVs, vans and commercial vehicles.

An expansion valve regulates the flow of refrigerant into the air-conditioning evaporator. It creates a pressure reduction that allows the refrigerant to absorb heat as it passes through the evaporator, helping the vehicle's air-conditioning system cool the cabin.

Depending on the system design, an expansion valve may regulate refrigerant flow in response to operating conditions.

 Different vehicles use different valve configurations, connection arrangements and refrigerant specifications.
