How a TXV Works
A thermostatic expansion valve (TXV) is a critical refrigerant-side component that meters the flow of liquid refrigerant into the evaporator coil. By sensing suction line temperature and pressure, the TXV modulates refrigerant flow to maintain a set superheat level — protecting the compressor while maximizing evaporator efficiency. The Trane VAL11814 is factory-calibrated to deliver precise, repeatable performance in compatible 2-ton systems.
