5. CONTROLS AND ELECTRICAL
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-

button is held.
The portion controls are factory programmed to the following default settings:
