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. When the WS1MR control valve is manufactured as a softener,
the control valve can be ordered to perform downflow or upflow regeneration. The WS1.25MR control valve is only
available in downflow regeneration. When the WS1MR or WS1.25MR 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 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 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 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  com  parable  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  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 non-volatile memory. The control valve does not need batteries.

The control valve‟s unique design and electronics allow the OEM to select:

1. a pre or pos

t ﬁll option with up or down ﬂow and adjust the length of the cycles; or

a pre or post ﬁll option, select a program code that has a preset cycle order/value and adjustable ﬁll cycle.

Tables 1 and 2 show examples when the valve is set up as a softener or a filter.
