All UF-1 and UFB-1 valves have a 24 volt solenoid that should be powered by an 80 kVA rated transformer. Voltage at the coil with the solenoid energized should be 22 and 27 VAC.

5.1 UF-1 and UFB-1 Portion Control Valve

The UF-1 and UFB-1 Portion Control Valves are push and release that dispense for a programmed duration. There are four settings: small, medium, large, and extra-large. There is also a Cancel/Pour rectangular button with red and green arrows. If this button is pressed during dispensing, the flow stops. If the valve is not dis- pensing and the button is pressed, the valve dispenses as long as the button is held.

The portion controls are factory programmed to the following default settings:

Portion Size	Pour Time
S	2 sec.
M	3 sec.
L	4 sec.
XL	6 sec.
