External connections Twin pilots
3. Description
3.1. Valve versions
3.1.1. Twin pilots
The pressure distributor pilot is mounted directly on top of the V132, in this case inlet water is the
control fluid and feeds the pilot circuit from the top collector. A controller with a proper camshaft
(called twin pilot camshaft) must be mounted on top of the valve and linked to the pilot stems. The
rotation of the camshaft moves the stems of the pilots in/out the pilot circuit, deviating the control
water inside the proper side of the V132 pressure chambers to move the pistons of the valve according
to the various cycles/phases.
3.1.2. External connections
There are four quick connection ports on top of the valve, each port is linked to a pressure chamber
inside the valve. The hydraulic distributor with pilots has to be mounted remotely from the valve, the
pilot ports can be connected to valve ports with a diameter of 6 mm flexible tubing.
The remote camshaft can control up to 4 pilots hence more valves can be controlled with a single
distributor. For this reason this configuration is generally used to:
• add outlet shut off pneumatic valve;
• add bypass during regeneration;
• control a valve in the suction line and make a timed brine draw.

3.5. System regeneration cycle (5-cycle operation)
Service — normal use
Untreated water is directed down through the resin bed and up through the riser tube. The hardness
ions attach themselves to the resin and are removed from the raw water being exchanged on the resin
beads against sodium ions. The water is conditioned as it passes through the resin bed.
Backwash — cycle C1
The flow of water is reversed by the valve and directed down the riser tube and up through the resin
bed. During the backwash cycle, the bed is expanded and debris is flushed to the drain, while the
media bed is remixed.
Brine draw— cycle C2
The controller directs water through the brine injector and brine is drawn from the brine tank. The
brine is then directed down through the resin bed and up through the riser tube to the drain. The
hardness ions are displaced by sodium ions and are sent to the drain. The resin is regenerated during
the brine cycle. Then the slow rinse phase starts.
Slow rinse — cycle C3
The slow rinse cycle allows the brine to be slowly pushed into the resin bed, enabling regeneration of
the resin.
Rapid rinse — cycle C4
The valve directs water down through the resin bed and up through the riser tube to the drain. Any
residual brine is rinsed from the resin bed, while the media bed is recompacted.
Tank refill — cycle C5
The SFE-EV-VIRIDION timer automatically calculate the refill cycle duration. Water is directed to the
brine tank, though the BV, at a flow rate controlled by the refill controller [BLFC], to create brine for
the next regeneration. During brine refill, treated water is already available at the valve outlet.
Note
Depending on controller programming (see 6.4.3. Advanced programming, variables:
Variable brining function & “BLFC size”, page 62), the refill cycle is performed before the
regeneration start, in this case refill is indicated as cycle 1B or after the cycle 4C, in this case
is indicated as cycle 5C.
In case refill is performed before the regeneration, after the 1B cycle is completed, the
controller & the valve will be still in service for a relative short time in order to wait the
necessary time to dissolve the salt in the refilled water.

Note
Please consult your resin manufacturer specifications to ensure that no additional
pretreatment prior to softening is required.

26 / 110 Ref. MKT-IM-009 / C - 08.06.2018
Installer Manual Siata V132-SFE-EV-VIRIDION - System sizing
The below sizing method can be applied for both residential and industrial softeners.
The sizing of a softener must be based upon certain parameters:
• inlet water hardness;
• peak flow rate and nominal flow rate;
• service velocity;
•salt dosage.
The softening and regeneration reactions are driven under certain conditions. To allow these
reactions to take place, make sure that the velocity is convenient during the different phases for
proper ion exchange. This velocity is given in the resin manufacturer specifications sheet.
Depending on the inlet water hardness, the service velocity for standard softening must be between:
Service velocity
[bed volume per hour]
Inlet water hardness
[mg/l as CaCO
]
3
°f
°TH
°dH
8 - 40 <350 <35 <19.6
8 - 30 350 to 450 35 - 45 19.6 - 25.2
8 - 20 >450 >45 >25.2
Note
Failure to respect the service velocity will lead to hardness leakage or even total softener
inefficiency.
Note that the water supply piping size may also be useful when estimating the nominal flow rate, since
the size of the piping allows a maximum flow rate to pass. Assuming the maximum velocity of water
in pipes is about 3 m/s, a good estimation for most common pressure [3 bar] and temperature [16°C]
is:
Piping size (internal diameter) Max. flow rate
[in] [mm]
[m3/h at 3 m/s]
0.5 12 1.22
0.75 20 3.39

1.5 40 13.57
2.0 50 21.20
2.5 63 34.2
3.0 75 49.2
4.2.2. Determining the required volume of resin
When sizing a softener, make sure that the volume of resin in the tank (bed volume) will be sufficient
so that even when the peak flow rate is reached, the velocity is still between the above values
depending on the hardness. When sizing a softener, always choose the resin volume and tank size
based on the peak flow rate but not on the nominal flow rate.
Note
Sizing on the nominal flow rate without taking the peak flow rate into account would result
in choosing smaller tank size and resin volume, and may lead in severe hardness leakage
during the service cycle when the peak flow is reached.
The maximum softened water flow rate that a softener can produce is given by the following formula:
Q
service max
= Fs
service
x BV
with:
Q
Fs
BV: bed volume of resin [m
: service flow rate [m3/h]
service max
: service velocity [BV/h]
service
3
]
Knowing this required volume of resin, it is possible now to determine the tank you need. Note that at
least a third of the total volume of the tank must be kept as free space so that the bed expansion
during backwash is sufficient to ensure correct cleaning of the resin.

4.2.3. Resin exchange capacity and capacity of the unit
The resin exchange capacity and capacity of the unit are two different things that should not be
confused. The resin exchange capacity is the amount of Ca
of resin, which will depend on the resin type and salt dosage, whereas the capacity of the unit is the
capacity of the system, which will depend on the volume of resin and resin exchange capacity.
Knowing the required volume of resin, you can determine the exchange capacity of the unit. The
capacity of the unit can be expressed in different ways:
• the mass capacity, which corresponds to the weight in equivalent CaCO
resin, expressed in kg as CaCO
;
3
• the volume capacity, which represents the maximum amount of water that can be treated
between 2 regenerations. This last capacity takes into account the hardness of the water to be
treated and is expressed in m
3
or litres;
• the combined capacity, which represents the volume of water that could be treated between 2
regenerations if the inlet hardness is 1 °f or °dH. This capacity is expressed in °f.m
The resin exchange capacity will depend on the amount of salt to be injected into the resin bed during
the regeneration. This amount of salt is given in grams per litre of resin. The next table is showing the
resin exchange capacity in function of the amount of salt for a system with standard efficiency
regeneration.
