TXV Valve Thermostatic Expansion Valve



Thermostatic Expansion Valve RFKA03E-3.4-10


At OzSupply Australia we stock the Thermostatic Expansion Valve RFKA03E-3.4-10. RFKA series thermostatic expansion valves are used to adjust mass flow of refrigerant into the evaporator while controlling the refrigerant´s superheat at the outlet of the evaporator. They can be used for various refrigerants under all working conditions. Possible applications are refrigeration systems like freezers, ice makers, dehumidifiers as well as air conditioners and heat pumps at various evaporation temperature ranges
