Four Seasons 38610 Expansion Valve
The Four Seasons 38610 A/C expansion valve is a TXV-style HVAC flow restrictor built for R134A systems. It uses a brass body and an 8.0 super heat setting to regulate refrigerant flow at the evaporator for stable cabin cooling.
Compatible with select Audi, BMW, Chevrolet, Geo, Isuzu, Mazda, Porsche, Volkswagen, and Volvo applications, this Four Seasons Expansion Valve 38610 is a direct-fit service part for older R134A air conditioning systems.
