Expansion Valve

Act as a throttle between the high pressure and the low pressure sides of refrigeration systems, Frozcube thermostatic valves control the superheat of refrigerant vapor at the outlet of the evaporator and ensure the refrigerant flow rate into the evaporator exactly matches evaporation's rate of liquid refrigerant in the evaporator. Therefore, the evaporator is fully utilized and no liquid refrigerant will be inhaled to the compressor. The expansion valves perceive the superheat of gas refrigerant in the evaporator's outlet via sensing bulb, thus auto regulate the refrigerant flow that enters the evaporator. Therefore， the valves are especially suitable for liquid injection in “dry” evaporators, where the superheat at the evaporator outlet is proportional to evaporator load.
