WebJun 11, 2024 · A: A TXV (TEV) is a type of metering device. The metering device's job is to create a pressure drop from the liquid line into the evaporator, which will result in refrigerant boiling (changing from liquid to vapor) through the majority of the evaporator coil. This low-temperature “boiling” absorbs heat from the space or product being cooled. WebThe thermostatic expansion valve, also known as a TXV valve, is a component within a refrigeration device that controls the amount of refrigerant that enters into the system. When the TXV valve is faulty, the evaporator within the system can either have too much refrigerant or not enough.
