LFTEV Thermostatic Expansion Valves

The thermal expansion valve is used to egulate the supply of liquid refrigerant in the evaporator. The supply is controlled by the superheat of the refrigerant so this valve is especially suitable for the supply of refrigerant liquid in the dry evaporator, because the superheat of the refrigerant at the outlet of the dry evaporator is proportional to the load of the evaporator.
