INCIDENT
8. Salted water in
in service line
9. No brine draw
10. The valve
regenerates
constantly
11. Constant leakage
to the drain
Options
Hot water available only on the 4600 valve:
The use of specific materials allows the valve to work at temperatures higher than 43°C: Up to
82°C for a timeclock version or 65°C for a metered version.
Immediate Regeneration:
As opposed to time clock or metered valves that regenerate at 2 A.M. this option allows the
valve to regenerate immediately after the set capacity is consumed
Fast Regeneration (FR):
This option allows the valve to regenerate in 90 minutes instead of 180 minutes. This valve can
only be fitted with vessels up to 10".
Low water usage piston (L.W.U.):
With this piston, water consumption during regeneration can be reduced.
