RFKH series thermostatic expansion valves are used to regulate refrigerant flow rate 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. Typical applications are refrigeration systems like commercial refrigerators and freezers, icemakers, air conditioners and dehumidifiers at various evaporation temperatures
- STAINLESS STEEL CAPILLARY AND SENSING BULB
- COMPACT DESIGN WITH INTERCHANGEABLE ORIFICE
- VALVES WITH MOP FUNCTION CAN BE PROVIDED TO ASSURE RELIABLE COMPRESSOR OPERATION
- THERMAL SENSING BULB UTILIZES CROSS CHARGE TECHNOLOGY, PROVIDING CONSISTENT SUPERHEAT CONTROL OVER WIDE EVAPORATOR TEMPERATURE RANGE
