Fleck 3900
Fleck 3900 Series 3” Commercial Control Valves
Fleck’s 3900 valve is ideal for commercial and industrial water softeners and filters with service flows up to 250 GPM and backwash requirements up to 100 GPM. The valve body is offered in rugged mechanical designs, with SXT electronic programmable options where applicable for extended settings and configuration capabilities.
Fleck Control Valves automatically control the backwash and regeneration cycles for media filters and water softeners to keep your water treatment system working at optimal performance all the time. Fleck control valves are available in time-clock options and metered options for on-demand regeneration based on water volume used.
Manual operation, dP triggered regeneration, interlocking, series and remote start regeneration configurations are available upon request.
