POP-8300 Free Chlorine online controller
- On-line analysis of municipal water tank disinfection
- Chlorine supplement control of pipe secondary pressurization (no negative pressure)



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

ZR type double tank floating bed control valve including ZR4-1/ZR4-1S(Side Loading), ZR10-1/ZR10-1S(Side Loading). It is equiped the inlet flow Meter and drainage flow meter, All the parameters is set by water volume, The double swap tank is for Alternating regeneration. Continuous water production, Water quality is stable , Adapted to the to high hardness water softening, such as the steam boiler and heating engineering and production process water.

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

For complex industrial processes, sewage treatment, water reuse, environmental monitoring, industrial field control, chemical process, thermal detection and discrete control, data transmission control and remote data transmission.

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


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.
