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).
