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
V250 valve in the various applications
may be examinated.
1) Single softening: The system consists of
a basic valve V250A 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 controls an additional use
closure valve;
III. 4 pilots controls a use c a
suction closure.
2) Duplex: the system is made on two
columns, each of which is run by a V250A
valve. 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).
3) Duplex o triplex softening: these are
systems made on two or three columns,
and may be controlled by HYDRAULIC
DISTRIBUTORS connected to professional
electronics. Thus, it is possible to produce
h i g h l y c o m p l e x s y s t e m s , w h i l s t
maintaining a high standard of quality.
4) Filtration: the considerations made
regarding softening are valid both for
single and duplex systems, with the
exception that in this case the suction of
the regenerator does not need to be
controlled.
