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 down
fl
ow regeneration water softener or
fi
lter.
The time clock control valve can be set to perform down
fl
ow regeneration or simply backwash. The time clock control valve has
two calendar options for regeneration frequency:
1. An option where the user can choose the number of days (1-99) between each regeneration; and
2. A seven-day option where the user can choose which day(s) of the week a regeneration should occur.
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 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 comes with a 15 foot power cord and is designed for use with the control valve. The AC adapter is for dry
location use only. The control valve maintains timekeeping for up to 8 hours if the power goes out and the battery is not depleted.
After 8 hours, the only item that needs to be reset is the time of day; valve status and programming are permanently stored in the
nonvolatile memory. If a power loss lasts less than 8 hours and the time
fl
ashes on and off, the time of day should be reset and the
non rechargeable battery should be replaced.
Table 1 shows the time for the backwash, regenerative, and rinse cycles for the ten available programming options. Six different
programs are available for a softener, one for a regenerative
fi
lter, and three programs for backwash only
fi
lters. When the control
valve is used as a:
• Softener - one or two backwashes occur and re
fi
ll always occurs after the rinse cycle (P0 through P5)
• Regenerative Filter - one backwash occurs and re
fi
ll always occurs after the rinse cycle (P6)
• Backwashing Filter - one backwash occurs (P7 through P9)
