GR20\40\50\20T\40T series up flow regeneration fixed bed large valve series, water production range is 15T/ h-70t /h, the inlet flow meter is used to set the cycle of water production, slow backwash water and wash water, and the brine flow meter and the brine electric valve are used to specifically measure brine absorption and salt tank water supply.In the flow mode, the internal flow transducer realizes the switch of all stations as long as the amount of brine,the amount of slow washing water and the amount of washing water is set according to the volume (liter) of the swap tank. After the period of softening water amount (ton) is set 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.

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.

Salt and water savings by using 100% capacity of the tank in service before switching to the second tank
Regenerates immediately when needed for continuous soft water
Corrosion-free fiber-reinforced polymer valve body

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
