1865/F116Q3 ion exchange unit

Ion-exchange unit for water treatment: water passes through a housing filled with ion-exchange resin, and the ions dissolved in it are replaced by an equivalent amount of ions released by the media. Resin selection sets the specific task — softening, alkalinity reduction (decarbonization), partial or full desalination, nitrate or boron removal. When the media's exchange capacity is exhausted, the controls run a regeneration cycle and the unit returns to service.

Housings from 14 to 21 inches are rated for flow rates where household-size valves are no longer enough: the line adds 2-inch Runxin valves with capacity up to 10 m³/h, alongside 3/4 and 1-inch models. Valve mounting in this group is top. A larger housing holds more resin, so for the same raw water the unit runs longer between regenerations.

Design 1865/F116Q3: housing 18×65″, automatic Runxin F116Q3 valve with water meter, up to 4.5 m³/h, 1" connection, top mounting. The valve is designed for softening — regeneration of the ion-exchange load with reagent solution. Weight 44.374 kg.

Configuration within the line: vessel size 1865 (18×65″) with control valve Runxin F116Q3. On the same vessel size 1865 (18×65″) the line also offers Runxin F63C1, Runxin F63P3, Runxin F74Q3, Runxin F82B3 and others. The same control valve Runxin F116Q3 is fitted on 0835, 0844, 1044, 1035 and others.

On vessel size 1865 the closest alternatives to Runxin F116Q3 are Runxin F63C1 (water meter None instead of Yes, weight 44.434 kg instead of 44.374 kg) and Runxin F74Q3 (valve capacity up to 10 m³/h instead of up to 4.5 m³/h, connection 2" instead of 1", weight 52.43 kg instead of 44.374 kg).
