04 FUNCTIONAL PRINCIPLES TALEA / ODEA - LINE
Talea, Odea Giro
The solenoid valve has several functions and these are described in the following para-•
graphs. A mechanical overpressure valve is integrated in the electrical valve which opens
at approx. 18 - 20 bar.
When dispensing coffee and the hot water / steam valve is closed, the coffee valve opens •
at approx. 4 bar and the water is pressed through the brewing unit.
The overpressure valve in the steam pipe to the Milk Island protects the system against •
damage caused by pressure, the steam state overpressure is fed back to the fresh water
tank.
The multi-way valve opens selectively depending on the operating situation in the fl ow •
direction (dispensing) or against the fl ow direction (pressure release).
