Control Disc Indicator
A visual indicator on top of the control disc (black dot) shows
the state of the system at any time. The control disc rotates
clockwise. When the indicator dot is at the 12 o'clock position,
the Right Tank is in service. When it is between the 12 o'clock
and 6 o'clock positions, the Left Tank is in regeneration.
When the indicator dot is at the 6 o'clock position, the Left
Tank is in service. When it is between the 6 o'clock and 12
o'clock positions, the Right Tank is in regeneration.
Lower Valving Section
The lower valving section consists of Level 2, Level 3, Level 4 and Level 5 assemblies.
In the center, there is one regeneration control valve. This valve opens after four teeth on
the control disc have engaged. This valve then opens, and powers the regeneration cycle.
All of the other valves are pairs: one set for the Remote Tank and one set for the Main
Tank. For each media tank, there is an Inlet, Outlet, Drain and Check Stem valve (also a
downflow rinse valve on DFFR enabled systems.) The Inlet, Outlet and Drain valves are
all servo valves controlled by the control disc. The Check Stems are simple one-way
valves (check valves). Together, these valves control the flow of water into and out of
each media tank during service and regeneration.
Level 6
The final level of the valve is used to direct the normal service path of the
water. This can be either downflow or upflow. Since all regenerations are
counter-current, choosing the service direction also specifies the
regeneration direction. Downflow service is used with standard, non-
packed tank systems. For high efficiency, packed tank systems, upflow
service is specified.
