Sanhua RFK - 24019 Expansion Valve R134a (Int. Eq. - Flare - inch)

For precise and balanced control of liquid refrigerant in refrigeration systems, the Sanhua RFK - 24019 Thermostatic Expansion Valve provides efficient and stable expansion in systems running on R134a. With its internally equalized (internal equalizer) design and flare connections, it is used reliably in refrigeration and air conditioning applications.

Precise Superheat Control and Stable Cooling Performance

RFK series expansion valves automatically adjust the amount of refrigerant entering the evaporator according to the system load. Thanks to the temperature sensed through the sensing element and capillary tube, the superheat value is kept stable; this supports compressor protection and the energy efficiency of the system. Its internally equalized design provides balanced operation in compact refrigeration circuits with a low pressure drop, without the need for an additional external equalizer line.
