Sanhua RFKA02-5.2-32 Expansion Valve R407C (Int. Eq. - Solder - inch)

To precisely meter the refrigerant flowing to the evaporator in refrigeration and air conditioning systems, the Sanhua RFKA02-5.2-32 Thermostatic Expansion Valve provides stable superheat control with its R407C-compatible construction and externally equalized design.

Stable Superheat Control in R407C Systems

Thanks to its capillary-connected sensing element (sensing bulb), which detects the temperature at the evaporator outlet, the valve automatically adjusts the refrigerant flow under changing load conditions. This ensures that the evaporator is filled efficiently, prevents liquid floodback to the compressor and maintains energy efficiency throughout the system. It is used reliably in cold rooms, water chillers, air conditioners and commercial refrigeration applications.
