Description
The Carrier 332368-774 is an OEM Thermal Expansion Valve (TXV) Kit engineered for R-410A refrigerant systems. Designed as a direct factory replacement, this kit delivers accurate refrigerant metering to maintain optimal evaporator performance, protect the compressor from liquid slugging, and ensure consistent system efficiency across a wide range of operating conditions.
Why Choose an OEM TXV Kit?
A properly functioning thermal expansion valve is critical to the efficiency and longevity of any refrigeration or air conditioning system. The TXV modulates refrigerant flow in response to superheat at the evaporator outlet, preventing both flooding and starvation of the coil. Choosing a genuine Carrier OEM replacement guarantees compatibility, correct flow ratings, and factory-specified performance — eliminating the guesswork of aftermarket substitutes.
