ZR type double tank floating bed control valve including ZR4-1/ZR4-1S(Side Loading), ZR10-1/ZR10-1S(Side Loading). It is equiped the inlet flow Meter and drainage flow meter, All the parameters is set by water volume, The double swap tank is for Alternating regeneration. Continuous water production, Water quality is stable , Adapted to the to high hardness water softening, such as the steam boiler and heating engineering and production process water.

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.

Single stage RO controller used for conductivity monitoring and process program control .

Incorporates 2 time-tested, hydraulically-balanced pistons to independently pilot service flow and regeneration
For use with single or multiple tank systems
