Venturi
The Essential Series Solitaire valve uses a one-piece venturi design
to draw brine from the brine drum or cabinet into the resin tank
for regeneration of the resin. The design of the Solitaire valve
venturi and its location allow for easy access to the venturi and
replacement/cleaning if necessary without disassembling the
entire Solitaire valve. Refer to the Servicing Venturi Section for
details.
Level 4
The Level 4 contains 5 operating valves. These valves will seal
with other levels, but in each case, the valve’s shaft is captured
in the level 4. These valves include: inlet/by-pass, outlet valve
and spring loaded control valve. The servo valves are operated
by the control disc. Together these valves control the flow of
water through the system during service and regeneration.
Level 5
The level 5 creates a surface for the valves contained in
the level 4 to seal against. It also includes the brine port
connection and drain valve.
Level 6 / Base
The final level of the valve is used to direct the normal service
path of the water. Upflow is the standard flow direction.
Since all regenerations are countercurrent, the regeneration
direction will be downflow. Also holds the check stem.
