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.


High Cost-Effective ,widely used for chemical industry,paper making industry,industrial coating,pharmaceutical,food,beverage,municipal water,Environmental and so on.

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


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.


“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.




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