Externally Equalised Thermostatic Expansion Valve R134a R22 R407c R404A/R507
NRF(E) series thermal expansion valve is an integrated expansion valve, suitable for air conditioning, refrigeration, refrigeration and other fields. Thermostatic expansion valves regulate the injection of refrigerant liquid into evaporators. Injection is controlled by the refrigerant superheat. Therefore the valves are especially suitable for liquid injection in "dry" evaporators where the superheat at the evaporator outlet is proportional to the evaporator load.
