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.

1) Working Position : Service->Back Wash->Brine and slow Rinse->fast rinse->Refill softened water->service.
Downflow type .Working Position : Service->Back Wash->Brine and slow Rinse->fast rinse->Refill->service.
2) Using ceramic moving valve disk, small rotation torque.
3) Abrasion resistance of sealing surface, outstanding and long-lived deal.
4) It could be operated with pressure directly.

This series instruments are widely used for online pH/ORP monitoring in environment protection water treatment, pure water treatment, industrial process and so on.

Incorporates 2 time-tested, hydraulically-balanced pistons to independently pilot service flow and regeneration
For use with single or multiple tank systems
Backwashes softener tanks up to 36″ diameter
Continuous flow rate of 106 GPM

Widely used for chemical industry,pharmaceutical,food,beverage,industrial coating,municipal water,Environmental,etc.conductivity (resisitivity) online measuring and control. It is a small-scale, industry leading and High Cost-Effective conductivity/resistivity integration online controller.

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.

One kind of popular and cost-effective online pH/ORP controller.

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

Time-tested hydraulically balanced piston, seal and spacer design to pilot service flow and regeneration
