Electric Expansion Valve, Type AKVO 10
Functions
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 refrigerant
is modest, the valve will stay open during a fraction of the periode. 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.
