Operating principle
The dirt separator operating principle is based on the combined
action of a number of physical phenomena.
The internal element (1) consists of a set of radial reticular surfaces.
The impurities in the water, on striking these surfaces, get
separated, dropping into the bottom of the body (2) where they are
collected.
In addition, the large internal volume of DIRTCAL
flow speed of the medium thus helping, by gravity, to separate the
particles it contains.
The collected impurities are discharged, even with the system
running, by opening the drain cock (3); this procedure can even be
performed while the system is in operation.
The dirt separator is designed in such a way that the direction in
which the medium is flowing inside makes no difference.

Construction details
Low head losses and performance maintained over time
The high performance of the
dirt separator is based on
using the internal element
with reticular surfaces. The
principle of collision and
decantation
of
particles
makes the dirt separation
action
more
efficient
compared to the common
strainers. This performance is
constant over time unlike
common
strainers
which
instead get clogged by the
trapped
sludge,
thus
changing
the
functional
features.
The geometrical structure of
DIRTCAL
®
is such that the
flow speed inside it is slowed
down to help separate the
particles of impurities.
Geometric structure and large dirt collection chamber
The dirt collection chamber
has the following features:
- it is located at the bottom of
the device, at such a
distance
from
the
connections
that
the
collected impurities are not
affected by the swirling of
the flow through the mesh.
- it is large enough to offer an
increased
amount
of
collected dirt, which means
emptying
/
discharging
procedures are required
less often (in contrast to
strainers, which need to be
cleaned frequently).
- it is easy to inspect, by
unscrewing it from the valve
body for any servicing of the
internal element required in
the event of obstruction by
fibres or large particles of
dirt.
Separation of ferrous impurities
Dirt separators fitted with a magnet offer greater efficiency in the
separation and collection of
ferrous
impurities.
The
impurities are captured inside
the dirt separator body by the
strong magnetic field created
by the magnets inserted in
the special outer ring.
The outer ring can also be
removed from the body to
allow the decantation and
subsequent
expulsion
of
sludge while the system is still
running.
As the magnetic ring is
positioned outside the dirt
separator body, the hydraulic
characteristics of the device
are not altered.
The magnet of the flanged
version is fitted into a pocket.
For dirt dischange procedure,
the magnet can be extracted
from the pocket.
