6 Cycle Control Valve;
The reliable Excalibur Water Softener control valve provides direct
flow of water during regeneration. The Water Softener control valve
is constructed with durable corrosion resistant materials, epoxy
coated, the piston operated design assures positive, accurate
positioning even in turbidity water problem water supplies. The six
cycle Water Softener control valve sequence of operation is as
follows:
1. 1
st
backwash,
2. Draw/slow rinse
3. 2
nd
backwash
4. Fast rinse
5. Refill
6. Service.
Service;
The Water Softener service cycle is a down flow operation. The hard
water flows down through the Water Softener resin and is softened by
hard water ions such as calcium and magnesium attaching to the
Water Softener resin beads. Then the Water Softener must be put
into regeneration at which time the calcium and magnesium ions are
then exchanged for sodium ions and flushed to drain.
Regeneration:
The Water Softener first step of regeneration is the back wash cycle.
Water flow from the bottom to the top of the tank then out to drain,
washing out turbidity or iron and reclassifying the Water Softener
resin bed. The Water Softener has an automatic flow control in the
drain line that limits flow of back wash water to avoid possible loss of
resin.
The Water Softener second step or regeneration is brine draw and
slow rinse. The Water Softener control valve directs water through
the Water Softener brine injector mixing it with concentrated brine
from the brine tank and discharges into the top of the Water Softener
tank. The Water Softener brine flows from the top of the Water
Softener tank through the Water Softener resin bed and out to drain,
