Water Meter Disc

The frequency of regeneration can be adjusted without re-gearing the system. The
use of the water meter disc provides for multiple regenerations per 360º cycle on the
water meter. Each regeneration notch on a water meter disc will initiate a
regeneration when the regeneration start pawl drops into one of these segments and
Meter Meter
engages with the teeth of the control disc. The number of regenerations within the
Disc 1 Disc 5
360º cycle is indicated by the number of the water meter disc.
Regeneration Pawls
It is important to realize that there are two regeneration pawls: the regeneration start
Regeneration drive pawl
pawl and the regeneration drive pawl. The regeneration start pawl advances the
control disc enough to open the regeneration control valve. The water meter and
control disc advance together until the control disc uncovers one of the holes in the
ceramic disc located directly beneath the control disc. This opens the regeneration
control valve, which starts regeneration. Once the valve has opened, the
regeneration drive pawl continues to advance the control disc through the
regeneration cycle.
When open, the regeneration control valve allows water to pass through a nozzle
Regeneration start pawl
where it is directed to the regeneration turbine in the regeneration chamber. As the
regeneration turbine spins, it drives the regeneration drive pawl, which advances the

control disc.

Jet Regeneration

During the regeneration, water is used by the valve to control the sequence. For
Jet
regeneration
units equipped with Jet Regeneration, a 0.2 gpm regeneration flow control is used to
gearing &
limit the amount of water used. In addition to this small flow control, the regeneration
turbine
nozzle in the level 2, and the regeneration turbine in the level one are also modified
to accept these lower flow rates.
Normal
In non-Jet systems, a 0.4 gpm flow control, standard regeneration nozzle and an
regeneration
gearing &
open regeneration turbine are used.

The Jet feature is included with all CP Systems.
Control Disc
All internal valve positions are controlled by the Control Disc. As the control disc turns, it covers and
uncovers holes in the ceramic disc (located directly below the control disc), sending pressure signals to open
and close all internal valves. The sequence of regeneration and service configuration (alternating or
Overdrive) is based on the type of control disc installed.
