Data Sheet
Electric expansion valve
Type AKV 15 and AKV 20
For liquid injection into evaporators
AKV are electrically operated expansion valves
designed for refrigerating plants.
The AKV valves are normally controlled by a
controller from Danfoss’ range of ADAP- KOOL
controllers.
The AKV valves are supplied as a component
programme, as follows:
• Separate valve
• Separate coil with terminal box or cable
• Spare parts in the form upper part, orice and
lter
Valve capacity is indicated with a number
forming part of the type designation. The
number represents the size of the orice of the
valve in question. A valve with orice 3 will for
example be designated AKV 15-3. The orice
assembly is replaceable.
Features:
• Refrigerants: R134a, R22, R23, R404A, R407A,
R407C, R407F, R407H, R410A, R422B, R422D,
R438A, R448A, R449A, R449B, R450A, R452A,
R463A, R507, R513A, R513B, R515A, R515B,
R744.
• For a complete list of approved refrigerants,
visit https://store.danfoss.com/ and search for
individual code numbers, where refrigerants
are listed as part of technical data.
• The valve requires no adjustment
• Wide regulation range Replaceable orice
assembly
• Both expansion valve and solenoid valve
• Wide range of AC and DC coils

Electric expansion valve, Type AKV 15 and AKV 20
Function
Figure 1: Function
The valve capacity is regulated by means of pulse-width modulation. Within a period of six seconds a voltage signal
from the controller will be transmitted to and removed from the valve coil. This makes the valve open and close for
the ow of refrigerant.
The relation between this opening and closing time indicates the actual capacity. If there is an intense need for
refrigeration, the valve will remain open for almost all six seconds of the period. If the required amount of
refrigeration is modest, the valve will only stay open during a fraction of the period.
The amount of refrigeration needed is determined by the controller. When no refrigeration is required, the valve will
remain closed and thus function as a solenoid valve.
