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.


Fully adjustable, 5-cycle control delivers upflow backwash, downflow brining, slow rinse, rapid rinse, brine refill, and downflow service
Time-tested, hydraulically-balanced piston, seal and spacer, controls service flow and regeneration
Non-corrosive, fiber-reinforced polymer construction
Excellent flow rates (19 GPM continuous, 24 GPM peak)
Backwash capacity handles tanks up to 16″ diameter for softener, and filter


Meter and time dual mode, the meter mode, its inflow meter achieved all station can be set according to the water volume demanded , as long as set by the swap of tank volume (L) backwash water and wash water, set cycle running water volume(ton), according to the set value for each station after descending to the switch when the “0”, discontinued or no water stop decreasing and maintain. This series of products have beautiful appearance, high material precision of valve body parts, good strength and high temperature resistance, and the main valve body is connected with metal inserts with good maintainability.


ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.


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.


Versatile top or side mount is suitable for commercial or industrial applications
Backwash capacity accommodates tanks up to 63″ diameter
Flexible 7 or 12 day time clock or meter initiated regeneration
Ideal for most filter applications up to 42″




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.
