Thermostatic Expansion Valve RFKA Series


RFKA series thermostatic expansion valves are used to adjust the 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.

Features

  •  Thermal bulb utilizes cross charge technology, providing equal superheat degree over the whole evaporation temperature range
  •  Thermal bulb utilizes cross injection technology, and the whole vaporizing temperature range share the same superheat degree
  •  Valves with MOP function can be provided to prevent damages to compressor motor caused by excessive evaporation pressure
  •  Wide vaporizing temperature range
  •  Stable performance of superheat adjustment

General Specifications

  •  Applicable to all common HCFC and HFC refrigerants such as R22, R134a, R404A, R407C, R410A, R507
