What Is a TXV Valve?

A thermostatic expansion valve (TXV) is a critical refrigeration component that meters the flow of liquid refrigerant into the evaporator coil. By responding to suction line temperature and pressure, the TXV maintains the ideal superheat level, protecting the compressor from liquid slugging while maximizing heat transfer efficiency. A properly functioning TXV is essential to system capacity, energy efficiency, and equipment longevity.
