please define refrigerant when you set order.A thermal expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in refrigeration and air conditioning systems that controls the amount of refrigerant flow into the evaporator thereby controlling the superheating at the outlet of the evaporator. Thermal expansion valves are often referred to generically as "metering devices". TXVs are designed for a wide range of air conditioning, refrigeration, heat pump, and chiller applications.
