SERVICE MANUAL
GENERAL FEATURES
V260 valves are the essential elements in
b u i l d i n g t h e f o l l o w i n g s y s t e m s :
a) simplex, duplex or multi-tank softening
(decalcification) systems for domestic,
laboratory and industrial use;
b) simplex or duplex demineralisation and
dealkalisation systems for laboratory and
industrial use and all other uses requiring
water with characteristics of guaranteed
quality;
c) simplex or duplex filtering systems for
all of the previous applications.
The valves are made with materials that
guarantee utmost resistance and quality.
They are available with a vast range of
controllers for every operation phase of
service and regeneration, starting from
the simplest electronic basic controller
with weekly clock to the sophisticated
electronic controllers in various models
which enable volume, volume-time
c o n t r o l a n d s a l i n i t y c o n t r o l i n
MicroSiemens/cm, etc.
In the electronic systems, all the
intervention times of operation phases
can be programmed in relation to system
type and dimension.
For specific controller features, see the
relative controller section.

USE SPECIFICATIONS
The various possibilities for the uses of this
valve in the various applications may be
examined.
1) Single softening:
the system consists
of a basic valve V260A, and a timer
complete with a minimum of 2 external
pilots in different solutions, with which the
system may be personalised as desired.
In particular, varying the number of
external pilots, it is possible to obtain
the following personalisations:
I. 2 pilots controls only the movement
of the pistons of the valve;
II. 3 pilots also controls an additional
use closure valve;
III. 4 pilots controls a use c a
suction closure.
2) Duplex softening:
the system is
made on two columns, each of
which is run by a V260A. This is
controlled, with water or air, by a
timer with a minimum of 2 pilots per
valve.
The alternating duplex systems (one
column is in service while the other is
in regeneration or not in use), may
be controlled by the AQUA CUBIC
timer, which may be supplied in two
standard versions:
I. 5 pilots (AC5-02/05), run by volume.
The system allows for the use of two
brine valves plus a use closure valve
II. As a variation on this system, it is
possible to substitute the two brine
valves with two on-off hydro-
pneumatic valves for the
closing/opening of the suction duct,
using an AQUA CUBIC 7-pilot timer
(AC7-02/05).
1) Demineralisation and
Decarbonisation:
this is the
applicative sector in which the
characteristics of the V260 valve may
be best appreciated. In particular
the V260 for demineralisation is
supplied in two different solutions:
A) The V260D consists of a separated
top column and base column, both
however supplied with a two Ø 1”
connectors, allowing the installer the
possibility to choose the length of the
most suitable connecting pipe.
B) The V260D-BV with backwash
valve, (eliminites bypass water during
regeneration) consists of a top and
base column, as well as kit 5100-260.
Also in this case, the definitive
connection between the two parts
must be carried out by the installer.
The timer predisposed for
demineralisation is electronic with
external pilots, capable of controlling
an anionic and cationic column, can
control the level of conductibility
showing a valve in µsiemns/cm at
the exit of the system, and
regenerate the system automatically.
The number of pilots of the timer is
determined by the type of system
required
I. AQUA IONIC 5 pilots ( AI5-02/05 )
controls the two c an on-off
hydro-pneumatic use closure valve;
II. AQUA IONIC 7 piloti ( AI7-02/05 )
controls the two c an on-off
hydro-pneumatic use closure valve+
two on-off hydro-pneumatic valves
for the closing/opening of the
regenerator suction.
4) Filtration:
the considerations made
regarding softening are valid both
for single and duplex system, with the
exception that in this case the suction
of the regenerator does not need to
be controlled.
For further details regarding the
timers, see the table of timer choice.
N.B. Among the accessories of the
V260, note the idropneumatic valve,
the bypass of unpurified water
towards use, during the regeneration
phase, can be avoided.
