Product Description

Special
Features
of
the
MDV
3200A
Normally
Open
In
its
non
energized
state,
i.e.
in
absence
of
voltage,
the
valve
remains
in
open
position,
so
that
the
channel
of
the
nozzle
insert
is
not
blocked
by
the
tappet
tip.
The
liquid
in
such
a
situation
therefore
may
flow.
In
reality,
this
fact
does
not
represent
a
problem,
since
for
this
model,
usually
high
‐
viscous
media
are
processed
which
in
worst
case
drain
off
very
slowly.
It
is
recommended
however
that
you
bear
this
fact
in
mind
and
reduce
the
supply
pressure
to
at
‐
mospheric
pressure
during
longer
interruptions
and
before
switching
OFF
the
unit.
Quick
‐
Change
To
replace
the
nozzle
unit
(with
adjusting
nut,
insert,
tappet
guidance
and
O
‐
ring)
is
quick
and
easy,
as
this
unit
has
the
quick
‐
change
feature.
Afterwards
you
have
to
carry
out
the
adjust,
in
order
to
establish
a
convenient
position
of
the
unit
with
respect
to
the
tappet.
This
way
a
reproducible
pro
‐
cess
remains
ensured.
Highest
Flexibility
Due
to
the
modular
design
of
the
series,
nozzle
units
and
fluid
boxes
can
easily
be
exchanged.
This
allows
at
any
for
a
quick
adaption
of
the
system
configuration
to
new
applications.
A
comprehen
‐
sive
choice
of
accessories
is
also
available
for
special
situations.
These
modifications
can
be
performed
in
no
time,
avoiding
downtimes
for
the
process.
Ordering
the
equipment
already
at
an
early
stage
however
is
recommended;
do
not
forget
to
specify
the
relevant
data
(Valve
ID
etc.).
Consult
our
Technical
Support
beforehand,
if
special
parameters
have
to
be
taken
into
consideration.
Functionality
Independent
of
the
Position
The
functionality
of
the
valves
does
not
depend
on
the
fitting
position,
considerably
simplifying
the
integration
into
an
existing
process.
User
‐
friendly
Design
The
control
unit
does
not
give
rise
to
compatibility
problems
with
respect
to
the
other
components
of
a
complex
process
structure.
Service
is
possible
by
keypad
or,
thanks
to
the
integrated
RS
‐
232C,
by
remote
PC.
Comprehensive
Material
Selection
Only
the
best
materials
are
used
for
the
production
of
Vermes
Microdispensing
valves.
All
parts
in
contact
with
the
transported
medium
consist
of
high
‐
alloy
special
steel,
rust
‐
and
acid
‐
resisting,
or
modifications
of
high
‐
duty
polymers
of
the
PEEK
and
PTFE
family.
Seals
are
available
in
NBR,
EPDM,
Viton,
Silicon
and
Perlast.
For
nozzle
inserts,
special
steel,
plastics,
ceramics
and
PEEK
options
are
permanently
in
store,
allowing
for
perfect
tailoring
of
the
configuration
to
the
needs
of
the
particular
application.
