ROC-8221 Single Stage Double Channels RO Controller
ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.


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


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


Applicable to all kinds of small and medium-sized single-stage, double-stage reverse osmosis control system. With simple operation, complete measurement and configuration, highly integrated system


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


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


FLECK control valve 5600 softening water equipment generally uses fixed bed downstream
regeneration, the working process is operation, backwashing, regeneration, replacement,
positive washing, salt tank water injection.


Easily-adjustable, 5-cycle, downflow-brining control
Rugged, long-life construction features a lead-free brass valve body
Uses conditioned water for regeneration


Widely used for electric power,electronics,metallurgy,petrochemical,pharmaceutical ,food and beverage,environmental protection field.


DR20\40\50\20T\40T Soften valve series is floating bed, all appearance and geometric parameters and parts is the same as the corresponding GR20\40\50\20T\40T, floating bed has a good water quality, to adapt high hardness of the raw water, configuration swap tank should be fine and high, runing velocity in the 30-60 m/h, but resin filling rate must be above 90%, being stable working pressure,The floating bed is not suitable for frequent starting and changing water consumption.
