Description :

Model ERF/FRFW thermal expansion valves are used to adjust the liquid refrigerant supply volume to the evaporator and they are suitable to various refrigerants and different charging condition. It meets the requirements of the cold storage facility, ice maker and dehumidifier as well as the refrigeration and air conditioning requirements under varied evaporation temperature.

Application :

•   High quality diaphragm is from same famous brand supplier .

•   The big power head structure with perfect linear performance has a stable adjustment on the degree of superheat.

•   New structure has large scope of evaporation temperature and big work amplitude under low temperature.

•   With proprietary technology, the diaphragm movement hysteresis <0.5°C and the valve has good stability.

•   The bonnet features fool-proofing design to prevent loss and ensure the reliability of secondary sealing.
