FLECK 2850
FLECK 2850
The Fleck 2750 is a heavy-duty, 1.5" commercial and industrial control valve designed primarily for high-flow water softening and media filtration systems. Constructed from solid, lead-free brass, it is engineered for long-term durability in light industrial, commercial, and RO (Reverse Osmosis) pretreatment applications.

5-Cycle Regeneration Sequence
- Backwash (Upflow): Reverse the water flow to loosen the media bed and flush out accumulated sediment to the drain.
- Brine & Slow Rinse (Downflow): Draws the concentrated brine solution from the brine tank via the injector system to regenerate the resin, followed by a slow rinse.
- Rapid Rinse (Downflow): Flushes out any residual brine or hardness from the media bed.
- Brine Tank Refill: Directs water back into the brine tank to dissolve salt and prepare the brine solution for the next cycle.
- Service: Returns the tank to standard production flow.
