1.2. Product Characteristics
Simple structure and reliable sealing
It 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 refill is controlled by electronic ball valve
During service, electronic ball valve will control to start the brine refill
so as to shorten the regeneration cycle time. 63515/63615 brine refilled
with hard water, 73515/73615 brine refilled with soft water.
Variety of installation methods
Use side-mounted connector to change the valve from top-mounted
to side-mounted. Screen is moveable.
Manual function
Realize regeneration immediately by pressing “ ” at any time.
Long outage indicator

MODEL 53515/53615/63515/63615/73515/73615

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 set parameters do
not need to reset. The process will continue to work after power on.
LED dynamic screen display
The stripes on dynamic screen flash, they indicate 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 all models 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
“ ”and“ ” 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. (Application refers to Figure
3-9)
Signal output(Take F99A/D as example)
There is a signal output connector on main control board. It is
applied for controlling external wiring (Refer to Figure 3-1 to Figure 3-8).
There are two kinds of output modes: b-01 mode: Turn on when
start regeneration and shut off at the end of regeneration; b-02 mode:
Signal is only available at intervals of each status.

MODEL 53515/53615/63515/63615/73515/73615

Remote handling input
This connector can receive external signal, used together with PLC,
and computer etc. to control the valve. (Application refers to Figure 3-11)
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 booster pump was 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
Figure 3-10)
All parameters can be modified
According to the water quality and usage, the parameters in the
process can be adjusted.
Four kinds of meter type can be selected (Suit for 63615/73615)

step ②.
④Install drain pipeline (If no special requirement, the standard DLFC is
No.7703)
a. Based on the table on P26, if tank diameter is 900 mm, install as step
d. If the tank size is 750 mm or 1000mm, you need to ask supplier for
another injector & DLFC. Install it as below steps.
b. Change 7703 to the corresponding injector for the tank which is 750
mm or 1000mm.
c. Change DLFC to the corresponding DLFC for the tank which is 750
mm or 1000mm..
d. Insert drain line flow
control into drain hose
connector, then screw it into
drain outlet, and lock it.
e. Glue the drain outlet with
UPVC (DN40). Put drain
outlet pipe to sewer as
