Control Valve Function and Cycles of Operation
This glass fi lled Noryl
1
(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. When the WS1CI control valve is manufactured as a softener, the control valve can be ordered
to perform downfl ow or upfl ow regeneration. The WS1.25CI control valve is only available in downfl ow regeneration. When the
WS1CI or WS1.25CI 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.
It is not recommended to change control valves from downfl ow to upfl ow brining or vice versa in the fi eld. The valve bodies
for downfl ow and upfl ow are unique to the regeneration type and and should not be interchanged. A mismatch of valve body
and regeneration piston will result in hard water bypass during service.
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 and 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. The control valve remembers all settings for two hours if the power goes out. After
two hours, the only item that needs to be reset is the time of day; all other values are permanently stored in the nonvolatile memory.
The control valve does not need batteries.
The control valve’s unique design and electronics allow the OEM to select the regeneration cycle sequence, as well as the cycle
times. The regeneration cycles available are:
• Backwash
• Rinse
• Downfl ow Brine
• Upfl ow Brine (WS1CI only)
• Fill/Regenerant Refi ll (this cycle can be set for either pre- or post-regeneration)
• Softening/Filtering (cycle used when regenerant is added just prior to the control valves scheduled regeneration). The cycle time
entered should be long enough to dissolve the regenerant being used. Note: The control valve is in service during this cycle.
• End (will complete regeneration process and return control valve to service position)
Tables 3 and 4 show examples when the valve is set up as a softener or fi lter.
