Product Description

Special Features of the MDV 3200 series
Normally Open
In its not 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 users bear this fact in mind, and reduce the supply pressure to
atmospheric pressure during longer interruptions and before switching OFF the unit.
Quick-Change
Replacement of the nozzle unit
(with adjusting nut, insert, tappet guidance and O-ring)
is quick and
easy, due to the quick-change feature of this unit. Afterwards the user has to carry out the adjust,
in order to establish a convenient position of the unit with respect to the tappet. This way a repro-
ducible process remains ensured.
Highest Flexibility
Due to the modular design of the series, nozzle units and fluid boxes can be exchanged easily. This
allows at any time for a quick adaption of the system configuration to new applications. A compre-
hensive choice of accessories is also available for special circumstances.
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.
Secure Wiring
The MDVs are equipped with high-quality Lemo connectors. Those can be connected and discon-
nected easily, but hold secure against any accidental opening.
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 PE, PEEK and PTFE fami-
ly.
•
Seals are available in different materials.
•
For nozzle inserts, special steel, stainless steel, ceramics and PEEK options are perma-
nently in store, allowing for perfect tailoring of the configuration to the needs of the par-
ticular application.
