What Is a TXV?
A thermostatic expansion valve (TXV) is a critical refrigeration component that meters the flow of liquid refrigerant into the evaporator coil. By maintaining a consistent superheat level, the TXV maximizes heat transfer efficiency, protects the compressor from liquid slugging, and helps the system adapt to varying load conditions. Using a genuine Lennox TXV ensures compatibility and preserves equipment warranty.
