This valve is intended to cut feed water supply during regeneration of the purification system, and will not let the feed water be supplied to the consumer. It is applied in all the backfill filters with CE1″ and CE125″ reagent control valves. The valve is used in manufacture of the DUPLEX, TRIPLEX and other systems, as well as in the schemes related to operation for storage tanks.

To prevent supply of unpurified water to consumer during regeneration of one of the filters, at the outlet line of each filter NHBP (no hard water bypass) valve is installed. The NHBP valve is connected with the cable to the special connector of the filter’s control valve. In the beginning of regeneration, the control valve switches the NHBP valve into the off-state. By this, it blocks the access of unpurified water to consumer. After the regeneration the NHBP valve returns to its on-state.  



The valve requires regular maintenance which involves thorough cleaning of the flow distributor and other elements of the valve. The service should be performed by qualified staff.
