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.

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


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

1) Working Position : Filter->Back Wash->Fast Rinse->Filter
2) Using ceramic moving valve disk , small rotation torque
3) Abrasion resistance of the sealing surface, outstanding and long-lived deal.
4) It could be operated with pressure directly.


Turbidity is the expression of suspended objects in water to the degree of obstruction of light transmission. This product uses RS485 interface to communicate with the digital sensor, high data accuracy, strong anti-interference, can directly control the digital sensor calibration and automatic cleaning and other functions.

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