Notice
To ensure normal operation of the valve, please consult with professional
installation or repairing personnel before use it.
If there are any of pipeline engineering and electric works, there must be
finished by professional at the time of installation.
Do not use the control valve with the water that is unsafe or unknown
quality.
Depending on the changing of working environment and water
requirement, each parameter of softener should be adjusted accordingly.
When the water treatment capacity is too low, please check the resin. If
the reason is shortage of resin, please add; if the resin is turn to reddish
brown or broken, please replace.
Test water periodically to verify that system is performing satisfactorily.
Ensure that there is solid salt all the time in the brine tank in the course of
using, when this valve is used for softening. The brine tank should be
added the clean water softening salts only, at least 99.5% pure, forbidding
use the small salt.
Do not put the valve near the hot resource, high humidity, corrosive,
intense magnetic field or intense librations environment. And do not leave it
outside.
Forbidden to carry the injector body. Avoid using injector body as support
to carry the system.
Forbidden to use the brine tube or other connectors as support to carry
the system.
Please use this product under the water temperature between 5～50℃,
water pressure 0.2～0.6MPa. Failure to use this product under such
conditions voids the warranty.
If the water pressure exceeds 0.6Mpa, a pressure reducing valve must

MODEL 51240B/53540B/53640B/61240B/63540B/63640B
2
be installed before the water inlet. While, if the water pressure under
0.2MPa, a diaphragm pump must be installed before the water inlet.
It is suggested to install PPR pipe, corrugated pipe or UPVC pipe,
instead of TTLSG pipe.
Do not let children touch or play, because carelessness operating may
cause the procedure changed.
When the attached cables of this product and transformer are changed,
they must be changed to the one that is from our factory.
1. Product Overview

1.2. Product Characteristics
Simple structure and reliable sealing
The distribution valve adopts hermetic head faces with high degree
pottery and corrosion resistance for opening and closing. It combines with
Service, Backwash, Brine Draw, Slow Rinse, Fast Rinse and Brine Refill.
No water passes the valve during regeneration in single tank
type.
Brine refilling is controlled by electric ball valve.

MODEL 51240B/53540B/53640B/61240B/63540B/63640B

Brine refilling is controlled by electric ball valve, refilled when in service,
shorten the regeneration time.
Brine refilling and service are operating in the meanwhile, for fixed bed,
the water for brine refilling is hard water.
Fixed bed regeneration softener could be converted to filter
system.
Blocking the brine line connector of 61240B/63540B/63640B,
removing the drain connector, the valve could be converted to filter system.
Manual function
Realize regeneration immediately by pushing “ ” at any time.
Long outage indicator
If outage overrides 3 days, the time of day indicator “12:12”will flash to
remind people to reset new time of day. The other parameters do not need
to be reset. The process will continue to work after powering on.
LED dynamic screen display
The stripe on dynamic screen flashes, which indicates the control
valve is in service, otherwise, it is in regeneration cycle.
Buttons lock
No operations to buttons on the controller within 1 minute, button lock
indicator lights on which represents buttons are locked. Before operation
press and hold the “ ”and“ ” buttons for 5 seconds to unlock. This
function can avoid incorrect operation.
It can choose time clock type or meter type by program selection
When all symbols light on, press and hold “ ” and “ ” buttons more
than 2 seconds to enter the menu of valve model selection. Press
“ ”or“ ” buttons to select the requested model, then press “ ” button to
save the selection. Reconnect the power, the model will be showed on
display board.

Interlock function
It has a function of interlock to realize only one valve in regeneration
but the other valves are in service while several valves parallel in system.
In multi-steps treatment systems such as RO pre-treatment, when several
valves are in series, there is only one valve in regeneration or washing to
ensure pass water all the times while different valves in regeneration or
washing.(Application refers to Figure 3-9)
Control signal output
There is a signal output connector on main control board. It is for
controlling external wiring (Refer to figures from Figure3-1 to Figure 3-8).
There are two kinds of output modes: b-01 Mode: Turn on at the start
of regeneration and shut off at the end of regeneration; b-02 Mode: Signal
is available only at intervals of regeneration cycles and in service.
Remote handling input
This connector can receive external signal, used together with PLC,
and computer etc. to control the valve. (Application refers to Figure3-11)
Pressure relief output
The valve will cut off feeding water to drain line when it switches in
regeneration cycles (Same as signal output b-02). Thus in some water
treatment system, e.g. deep well, one diaphragm booster pump was

MODEL 51240B/53540B/53640B/61240B/63540B/63640B
5
installed on the inlet to increase the system water feeding pressure, this
cut-off will cause pressure on inlet rising too fast to damage the valve.
Pressure relief output can be used to avoid this problem. (Application
refers to Figure3-10)
All parameters can be modified
According to the water quality and usage, the parameters in the
process can be adjusted.
Two meter types for option (Suit for 63640B/53640B)
Mode
Name
Instruction
A-01
Meter
Delayed
Regenerate on the day although the available
volume of treated water drops to zero (0).
Regeneration starts at the regeneration time.
A-02
Meter
Immediate
Regenerate immediately when the available
volume of treated water drops to zero (0).
Maximum interval regeneration days （Suit for 53640B/63640B）
Under the situation of service reaching the setting days and the
volume not yet, it could enter into regeneration process forcibly when
current time is the same as regeneration time.

hardness will hardly reach the requirement of boiler feed water (0.03
mmol/L). It is suggested to adopt second grade softener.
