ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.


Fully adjustable, 5-cycle control delivers upflow backwash, downflow brining, slow rinse, rapid rinse, brine refill, and downflow service
Time-tested, hydraulically-balanced piston, seal and spacer, controls service flow and regeneration
Non-corrosive, fiber-reinforced polymer construction
Excellent flow rates (19 GPM continuous, 24 GPM peak)
Backwash capacity handles tanks up to 16″ diameter for softener, and filter


Single stage RO controller used for conductivity monitoring and process program control .


Versatile top or side mount is suitable for commercial or industrial applications
Backwash capacity accommodates tanks up to 63″ diameter
Flexible 7 or 12 day time clock or meter initiated regeneration
Ideal for most filter applications up to 42″


Meter and time dual mode, the meter mode, its inflow meter achieved all station can be set according to the water volume demanded , as long as set by the swap of tank volume (L) backwash water and wash water, set cycle running water volume(ton), according to the set value for each station after descending to the switch when the “0”, discontinued or no water stop decreasing and maintain. This series of products have beautiful appearance, high material precision of valve body parts, good strength and high temperature resistance, and the main valve body is connected with metal inserts with good maintainability.


Widely used for online measurement of acid&alkali in low concentrations and the low viscosity single-phase fluid of non-trade settlement process.
