New RFKH20 series is suitable for A2L refrigerants 

New thermostatic expansion valves RFKH20 series are suitable for refrigerants R455A and R454C in temperature range N [from -40°C to +10°C] without MOP function.

The new series contains 6 different models with 3 different outlet connections types, with internal or external equalisation:

  • 1/2” SAE flare connection
  • ODF connection – Metric 12mm
  • ODF connection – Imperial 1/2”

RFKH series also includes:

  • RFKH08 series: models suitable for usage with R448A & R449A refrigerants
  • RFKH11 series: models suitable for usage with R452A refrigerant

RFKH series valves can be used for both cooling and air conditioning applications and are available for the main refrigerants currently on the market: R407C, R134a, R404A, R507 (a different version for R22 is available for non-EU markets).

RFKH series valves are configured as thermostatic valves with interchangeable orifices, a brass body, copper connections and a stainless steel head. The use of stainless steel in the bulb and capillary tube brings greater strength to the valve and reduces the risk of capillary tube damage in the event of accidental impacts or unusual vibrations.

The RFKH range also offers flexibility of choice in regard to types of fitting with a threaded inlet and outlet (SAE Flare), a configuration mainly used by installers, and with metric or imperial welded fittings.
