"V240" valves are the essential elements in building the following systems: 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
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 control and salinity control in 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 manual.

SPECIFIC OF USE
Making reference to the schemes of pag. 5 and 6, the varied possibilities of employment of this valve can be examined in the varied applications.
1) Single softening: the plant consists in a basic valve V240A, with or without bypass, and of a
timer furnished in different solutions, with which we succeed in personalizing the plant to our
Particularly the sketch to pag. 5 bring two variations of the same plant and that is:
; To the left we have the valve commanded by a timer climbed on directly on the
valve, on which has been preassemblato a double pilot.
; Instead we have to the right the same plant with a timer to 2 external pilots. The use
of the external pilots allows us of to vary the configuration of the plant in the following way,:
I. 2 pilots it commands the solo movement of the pistons of the valve
II. 3 pilots it also commands an additional valve of closing I use
III. 4 pilots it commands a closing I use + a closing aspiration
2) Softening duplex: the plant has realized on two columns every of which has managed with a
valve V240A. This last is comandabile, to water or to air, with a timer with a minimum of 2 pilots for every valve.
To pag. 7 have a plant duplex in alternate (a column is in service and the other one it is in regeneration or in pause), which is commanded by a timer AQUA CUBIC 5 pilots (AC5-02/05), managed to volume. The plant foresees the use of two valves brine.
How variation to this plant is proposed of to replace the two brines with two valves on-off idro-pneomatiche for the chiusura/apertura of the duct of aspiration using a timer AQUA CUBIC 7 pilots. (AC7-02/05)
3) Filtering : either for single fittings that duplexes are worth the considerations done for the sweetening, with the only variation that in this case it doesn't have each other from to check the aspiration of the rigenerante
4) Demineralizzazione and Decarbonatazione: This is the sector applicativo where better the
characteristics of the valve V240 are appreciated, in the fattispecie V240D.
The timer predisposed for the demineralizzazione is electronic to external pilots, able to command a column anionica and a cationica, can check the value of the conductibility noticing a valvore automatically in µsiemns/cm to the exit of the plant and rigenenerare the plant. The number of the pilots of the timer has determined from the type of plant that wants to get each other
I. AQUA IONIC 5 pilots (AI5-02/05) it checks the two columns + a valve on-off idro-
pneomatiche of closing I use
II. AQUA IONIC 7 pilots (AI7-02/05) it checks the two columns + a valve on-off idro-
pneomatiche of closing I use + two valves on-off idro-pneomatiche idro-pneomatiche
idro-pneomatiche for the chiusura/aperture of the aspiration of the rigenerantis
. For great details on the timers it is postponed to the chart of choice of the timers (pag. 22)
