The TCW type thermal expansion valve is suitable for all common refrigerants and is used to regulate the supply of liquid refrigerant in the evaporator.

The TCW thermal expansion valve automatically controls the refrigerant supply by adjusting the superheat.

The TCW expansion valve can be used in various scenarios such as water-cooled units, air conditioning systems, heat pumps, refrigerators, traditional refrigeration systems, etc.
