Electric Expansion Valve
Type AKVO 10
Valve designed for refrigeration plant
AKVO 10 is an electrically operated expansion valve designed for refrigeration plant.
AKVO 10 has an internal €lter.
The AKVO 10 range covers a capacity range from 0.6 – 13.5 kW (R404A/R507) and is divided in 7 capacities.
Features
• Refrigerants: R744, R22/R407C, R404A/R507, R410A, R134a, R407A, R23, R407F, R422B, R422D, R448A, R449A, R449B, R450A, R452A, R513A.
• The valve requires no adjustment
• Wide regulation range 10 – 100% of the full capacity
• Internal €lter
• Both expansion valve and solenoid valve
• Wide range for coils DC and AC

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 ƒow 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.
