    UF-1 and UFB-1 Valves Training Manuai 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 installing and maintaining a water filtration system.

    UF-1 and UFB-1 Valves Training Manual 1.2 Water Flow (cont.) Figure 7 The position of the piston inside the sleeve is determined by the upward pressure of the liquid against the base of the piston and the downward pressure of the spring inside the piston (not shown here). The pressure of the spring is regulated by the adjusting screw.
