Control Valve Function and Cycles of Operation
This glass filled Noryl1 (or equivalent) fully automatic control valve is designed as the primary control center to direct and regulate all cycles of a water softener or filter. The WS1EI and WS1.25EI control valves are only available in downflow regeneration. When the WS1EI or WS1.25EI control valve is set up as a filter, the control valve can be set to perform downflow regeneration or simply backwash. The control valve can be set to regenerate on demand (consumption of a predetermined amount of water) and/or as a time clock (passage of a particular number of days). The control valve can be set so that a softener can meet the Water Quality Association (WQA) Standard S100 or NSF/ANSI Standard 44 efficiency rating.
The control valve is compatible with a variety of regenerants and resin cleaners. The control valve is capable of routing the flow of water in the necessary paths to regenerate or backwash water treatment systems. The injector regulates the flow of brine or other regenerants. The control valve regulates the flow rates for backwashing, rinsing, and the replenishing of treated water into a regenerant tank, when applicable.
The control valve uses no traditional fasteners (e.g. screws); instead clips, threaded caps, nuts and snap type latches are used. Caps and nuts only need to be firmly hand tightened because radial seals are used. Tools required to service the valve include one small blade screw driver, one large blade screw driver, pliers and a pair of hands. A plastic wrench is available which eliminates the need for screwdrivers and pliers. Disassembly for servicing takes much less time than comparable products currently on the market.
Control valve installation is made easy because the distributor tube can be cut 12.7 mm (½”) above to 12.7 mm (½”) below the top of tank thread. The distributor tube is held in place by an
The AC adapter power pack comes with a 4.6 meter (15 foot) power cord and is designed for use with the control valve. The AC adapter power pack is for dry location use only.
Table 1 shows the order of the cycles and available time for the WS1EI or WS1.25EI control valve. The WS1EI and WS1.25EI can be used for downflow softener and filter applications as well as
