Continuous flow rate of 51 GPM with a backwash of 49 GPM

Flexible 7 or 12 day time clock or meter initiated regeneration
Fully adjustable, 5-cycle control delivers upflow back wash, downflow brining, slow rinse, rapid rinse and down flow service
Designed for single tank or multi-tank systems, alternating or interlocking
Continuous flow rate of 250 GPM

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

Easily-adjustable, 5-cycle, downflow-brining control
Rugged, long-life construction features a lead-free brass valve body
Uses conditioned water for regeneration

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.
