Battery Backup
The valve has a 9-volt battery back up to maintain the time of day, the flow rate, and the
system current data input during power interruptions.
24V Operation
Simplifies installations, maintenance and reduces electrical hazards
UL rated and approved transformer
Soft Water Service During Brine Making
• The brine making is a full contact time cycle immediately before regeneration needed, insuring
the correct amount of fresh saturated brine solution for a complete regeneration.
• During the brine making cycle service water continues to be delivered softened.
Brine Before Backwashing
• Full brining before backwash cycle increases regeneration efficiency because the resin bed is not
mixed with exhausted and active beads but remains properly separated in layers during the brine
cycle. As the beads swell during the full brine cycle the debris (i.e. iron) which may be attached to
the beads will be released and be removed more readily during the following backwash cycle.
• Brine make up before the system regenerates helps eliminate salt bridging and tank sweating
Soft Water Brine Fill
The ONLY Single Valve on the Market with Soft Water Brine Tank Fill
• Increases the brining efficiency in using softened water to fill the brine tank. During regeneration
of the resin bed the brine cycle only introduces brine and not hard water elements which take up
resin exchange sites limiting the service capacity of the system.
• Decreases the potential for debris to be introduced into the brine tank which can create mainte
nance problems with the safety float valve operation, injector screen clogging, brine valve set
wear, injector seating properly and/or clog brine flow control.
Pressure Regulated Injector
• Pressure regulation for consistent brining with varying water pressure applications maintaining
the accuracy and efficiency of the system capacity
• Pressure regulated Brining controls the flow and relative feedwater pressure to prevent fluidizing
of the resin bed and preserve the effective salt efficiency from the variable Upflow brining system
HIDDEN 5 th CYCLE
• Hidden 5 th Cycle of Fast Rinse eliminates hard water carry over and salt slug contamination to
the down stream service side of the system
• The 5 th cycle is a down flow fast rinse cycle which removes the hard water pocket from the
service flow which disrupts soft water delivery. Hard water in hot water heater takes 2-5 days to
purge
• This cycle also compacts resin beads for efficient softener operation only found in our upflow
valves.
