Electronic expansion valve Danfoss AKV 10-7 068F1180

Danfoss AKV 10-7 Electric Expansion Valve, 068F1180

The AKV is an electrically controlled expansion valve designed for refrigeration systems. The AKV valve is typically controlled by electronic regulators from the Danfoss ADAP-KOOL® series. The valve operates through pulse width modulation (PWM), meaning it is either fully open or tightly closed.

Applications:

• Traditional refrigeration systems
• Refrigeration chambers
• Water chillers

Advantages:

• AKV valves are provided according to the following component program:
  • Valve with replaceable nozzle
  • Separate coil
• Flexible MOP (Maximum Operating Pressure) regulation
• No adjustment required for the valve

Additional Information:

• AKV 10 valves cover a performance range from 0.8 kW to 12 kW (R404A/R507) and are available in 7 performance categories
• AKV 15 valves cover a performance range from 20 kW to 78 kW (R404A/R507) and are available in 4 performance categories
• AKV 20 valves cover a performance range from 78 kW to 494 kW (R404A/R507) and are available in 5 performance categories
• AKV valves are suitable for HCFC, HFC, and R744 refrigerants
