Control Valve Function and Cycles of Operation
1
This glass filled 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 filter. When the WS1CH control valve is manufactured as a softener, the control valve can be ordered to
perform downflow or upflow regeneration. The WS1.25CH control valve is only available in downflow regeneration. When the
WS1CH or WS1.25CH 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.
It is not recommended to change control valves from downflow to upflow brining or vice versa in the field. The valve bodies
for downflow and upflow 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 flow of
water in the necessary paths to regenerate or backwash water treatment systems. The injector regulates the flow of brine or other re-
generants. 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 and 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 ½" above to 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 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 until the battery power is depleted if the power goes out.
After the battery power is depleted, the only item that needs to be reset is the time of day; other values are permanently stored in the
nonvolatile memory. The control valve battery is not rechargeable but is replaceable.
The control valve's unique design and electronics allow the OEM the flexibility shown in Tables 3 and 4.
