4.2. Frother valve assembly
The milk is frothed as follows:
1) The steam goes through the frothing valve, thereby creating a depression that draws the milk
and a percentage of air
2) The milk is drawn from the carafe and is mixed with the air that is drawn through the slot on
the carafe connection.
3) STEAM - AIR - MILK are mixed inside the Venturi Pipe, thereby forming froth.
