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


Digital Laser Turbidity online analysis sensor,It can be used for on-line monitoring of water quality in different water bodies such as waterworks and membrane filtrate,The sensor internally completes all measurement calculation compensation


Time-tested hydraulically balanced piston, seal and spacer design to pilot service flow and regeneration
Solid, lead-free brass valve body for superior strength and durability
Backwash capacity handles tanks up to 30″ diameter
1-1/2″ top mount control valve ideal for smaller size commercial/industrial applications
Consistent brining regardless of salt levels with timed brine refills
Choice of 7 or 12 day clock, manual or meter
Continuous flow rate of 51 GPM with a backwash of 49 GPM


“One Dynamic and Two Static” Double Static Ceramics Plates Multi-port Valve is on behalf of another beginning in the field of water treatment control, which can overcome many disadvantages of traditional products in installation.


Meter, time clock dual mode. In flow mode, the internal flow transmitter realizes the function of setting water volume as required. After setting regeneration water volume and cleaning water volume of exchange tank, the period of softening water amount (ton) according to the hardness of the raw water, each station decreases to “0” according to the set value, and stops decreasing and maintains when the water is out of service or no water.


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


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


Flexible 7 or 12 day time clock or meter initiated regeneration
Fully adjustable, 5-cycle control delivers upflow back wash, downflow brining, slow rinse, rapid rinse and down flow service
Designed for single tank or multi-tank systems, alternating or interlocking
Continuous flow rate of 250 GPM


On-line analysis and process control of the oil refining, metallurgy,chemical synthesis industry process;
