UF-1 and UFB-1 Valves Training Manual 3. OVERVIEW 3.1 Product Description The UF-1 and UFB-1 valve provides accurate flow capability and dependability. The UF-1 and UFB-1 valves are capable of flow rates of 1 ½ to 3 ounces per second (high flow), 2 to 4 ounces per second (UFB-1), or 3 to 4 ½ ounces per second (ultra flow). The valve flow control modules are the only parts that differ in the three versions. Note: The flow rate is also dependent on the capacity of the dispensing, cooling, and

INTRODUCTION UF-1 and UFB-1 Valves Training Manual There are four varieties of UF-1 and UFB-1 valves: The cup activated valve dispenses by means of a lever engaged by the cup. A push button valve has a press and hold button on the front cover of the valve. TM The Optifill valve dispenses with an activation lever but stops after the liquid fills the cup and touches the lever A portion control valve has four programmable drink size buttons that provide timed deliveries, top off, and a m

SYSTEM DETAILS UF-1 and UFB-1 Valves Training Manual SYSTEM DETAILS 1. WATER 1.1 Water Quality Water quality issues have an affect on dispensing valves. Chloramine, a combination of chlorine and ammonia is responsible for some degradation of rubber components. Chloramine is used in many U. S. water supplies. Its affects can be minimized by install- ing and maintaining a water filtration system. Ultra pure water affects the sensitivity of the Optifill™ valve. Because ultra pure water has les

UF-1 and UFB-1 Valves Training Manual 2. SYRUP/CONCENTRATE Syrup should always be precooled before setting the ratio. Syrup takes a path through the valve parallel to the water path. It is introduced in the block, travels through a syrup flow control, banjo, valve head and out the nozzle. Note, concentrate is not cooled. High sugar syrups are more viscous (thicker) than diet syrups and consequently have more pressure drop within a system. This pressure drop results in less flow at the valve a
