Application
AKV are electrically operated expansion valves designed for
refrigerating plant.
The AKV valves can be used for HCFC-, HFC and R744-refrigerants.
The AKV valves are normally controlled by a controller from
Danfoss’ range of ADAP- KOOL® controllers.
Advantages
• The valve requires no adjustment
• Wide regulation range
• Replaceable orice assembly
• Both expansion valve and solenoid valve.
Function
The AKV valves are supplied as a component programme, as fol-
lows:
• Separate valve
• Separate coil with terminal box or cable
• Spare parts in the form upper part, orice and lter
The individual capacities are indicated with a number forming
part of the type designation. The number represents the size of
the orice of the valve in question. A valve with orice 3 will for
example be designated AKV 10-3.
The orice assembly is replaceable.
