RFGB Series Thermal Expansion Valve

The RFGB series thermal expansion valve is used to adjust the flow of liquid refrigerant into the evaporator, thereby controlling the superheat at the outlet of the evaporator. It can provide a variety of refrigerants and their charging under various working conditions. They are mainly used in refrigeration systems, such as commercial refrigerators, cold storages, and dehumidifiers. They can also be used in air conditioning and heat pump systems in various evaporating temperature ranges.
