Steam Valves
The Xpress uses three steam valves, referred to as the left, center, and
right steam valves. Each steam valve operates on the same voltage and
has a different orifice size for regulating the steam flow from the steam
tank.
During a latte pour, all three steam valves are activated and
engaged.
During a cappuccino pour, the left and right steam valves are
activated and engaged.
During a cold drink pour, only the left steam valve is activated
and engaged.
Left Steam Valve
Operating voltage: 24Vdc
Orifice size: 0.024” (.06cm)
This valve is open for both steamed and foamed milk production and the
valve remains open for a period of time after milk production is complete,
to clear milk from the tubing and the milk pump.
