Regeneration Drive Pawl
Regeneration Start Pawl
When open, the regeneration control valve allows water to pass through a nozzle 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.

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.

Meter Gearing
The frequency of regeneration can be adjusted without re-gearing the system. The use of the
water meter disc provides for multiple regenerations per 360° 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 engages with the teeth of the control disc.
The number of regenerations within the 360° 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 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.
Jet Regeneration
During the regeneration, water is used by the valve to control the sequence. For units
equipped with Jet Regeneration, a 0.2 gpm regeneration flow control is used to limit the
amount of water used. In addition to this small flow control, the regeneration nozzle in the
level 2 and the regeneration turbine in the level 1 are also modified to accept these lower flow
rates.
The Jet feature is included with all CP Systems.
Gear Alignment Clip
The Gear Alignment Clip is used to keep optimal spacing between gears. This minimizes
pressure loss and maximizes flow sensitivity.
