Fleck 5810 Control Valve

Product Description

The Fleck 5810 control valve is apart of a series of commercial valves that are designed to provide unmatched strength, prevent occurrences of corrosion, last for long durations, and resistance to ultraviolet. The features of this valve, which includes a 3 or 5 cycle control that improves the productivity and dependability of the water treatment system.

Fleck 5810

The Fleck 5810 commercial valve produces a flow rate of around 36 GPM with backwash capabilities of 28 GPM. The backwashing process is geared towards water softener tanks and water filters of under 22" in diameter. Double backwash is also incorporated to ensure a decrease in hardness leakages. These valves are proven to work through a diagnostic tool which displays historical valve performance.

How to Order Fleck Valve?
  • Inform us on the type of system that you are dealing with (water softeners or filters)
  • Clarify the precise flow rate required for your application
  • Specify the tank size that is being utilized to ensure the correct flow restrictor sizing
  • Fleck valve has a multitude of options so please discuss your application with Pure Aqua representative to offer the best options to fit your application.
