The AKVH 10 is an electrically operated expansion valve for CO2 refrigerant.

Technical specifications

  • R744 refrigerant
  • Tolerance of coil voltage is +10/-15%
  • Refrigeration capacity 0.4 kW to 11 kW
  • Freezing capacity 0.8 kW to 22 kW
  • Regulation range (capacity range) 10 to 100%
  • Evaporating temperature -60 to 60°C
  • Ambient temperature -50 to 50°C
  • Valve requires no adjustment
  • MOPD 35 bar
  • Max working pressure 10-0 to 6 PS = 90 barg (90 barg under stand still conditions, but under normal operating conditions, there must be liquid to the inlet of the valve)
  • Replaceable orifice assembly
  • Both expansion valve and solenoid valve
  • Wide range of coils for d.c. and a.c.


  • Reliable - Simplicity and robustness of the design reduce possible failures in the field
  • Durable – valve lifetime of minimum 10 years and 50+ million cycles
  • Proven – AKV valves have been on the market for 27+ years and over 2 million AKV valves are active in the field
  • Low leakage rate – 0.00001% leakage rate
  • Energy savings - 10% energy savings over TXV technology and 33% savings with full ADAP-KOOL® system
  • Coil with Electronic coil controller for lower valve noise level, energy saving, higher valve MOPD and longer valve lifetime


  • Commercial refrigeration
