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.


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


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.


CIT-8800 Inductive Conductivity / Concentration Online Controller is a new developed conductivity/Concentration/TDS/Temperature integration controller,with No electrode inductive Conductivity Sensor.
