Control Valve Function and Cycles of Operation
This glass fi lled Noryl

(or equivalent) fully automatic control valve is designed as the primary control center to direct and regulate
all cycles of a water softener or fi lter. The WS1EI and WS1.25EI control valves are only available in downfl ow regeneration. When
the WS1EI or WS1.25EI control valve is set up as a fi lter, the control valve can be set to perform downfl ow 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
As so ci a tion (WQA) Standard S100 or NSF/ANSI Standard 44 effi ciency rating.
The control valve is compatible with a variety of regenerants and resin cleaners. The control valve is capable of routing the fl ow
of water in the necessary paths to regenerate or backwash water treatment systems. The injector regulates the fl ow of brine or
other regenerants. The control valve regulates the fl ow 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 fi rmly 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 com pa ra ble products currently on the market.
Control valve in stal la tion 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 o-ring seal and the control valve also has a bayonet lock feature for upper
distributor baskets.
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 downfl ow softener and fi lter applications as well as backwash-only fi lters.
