AC Expansion Valves

AC Expansion Valves, found within the HVAC system of passenger cars and commercial vehicles, regulate the flow of refrigerant to the evaporator core. This precise metering ensures optimal cooling performance and prevents liquid refrigerant from entering the compressor, which could cause damage. Located downstream of the condenser and receiver-drier, these valves reduce refrigerant pressure and control its vaporization rate. Expansion valves utilize various technologies, including thermal expansion and orifice tubes, to achieve this control. Examples in our assortment include MAHLE MPN 70819216 for specific vehicle applications, Delphi TSP0695190 for precise refrigerant metering, and MAN 81619750252 for commercial vehicle HVAC systems. Proper function is critical for maintaining efficient and reliable climate control.
