An overfill protection valve for
underground storage tanks
This company offers a wide range
of brass, aluminum and stainlesssteel
safety valves for use in petrochemicals
facilities. The company's
Model 442 overfill protection valve
(photo, p. 54) is designed to prevent
the overfill of underground storage
tanks by providing a positive shutoff
of product delivery. The shutoff valve
is an integral part of the drop tube
used for gravity filling. The Model
442 is certified as a two-stage shutoff
valve. When the liquid level rises
to about 95% of the tank capacity,
the valve mechanism is released,
closing automatically with the flow.
The operator may then stop the filling
process and disconnect and
drain the delivery hose. As long as
the liquid exceeds the 95% level,
the valve will close automatically
each time delivery is attempted.
If the delivery is not stopped and
the liquid rises to about 98% of
tank capacity, the bypass valve
closes completely. No additional
liquid can flow into the tank until
the level drops below a reset point.

of the gummy product, and a special
agitator installed in the hopper helps
to loosen any clumped gummy products
and separate them one by one.
When compared to a typical checkweighing
system, a designated counting
machine can increase productivity
because loss rate is reduced. Hall 3.1,

Crossflow filters ensure high
product quality and yield
The Krauss-Maffei dynamic crossflow
filter (DCF; photo) is
suitable
for the clarification of liquids and for
concentrating and washing of solids
in a broad variety of chemical and
biochemical products. Whether the
targeted products are solid or liquid,
the Krauss-Maffei DCF increases
yield and product quality. The filters
offer extremely high yields and can
process highly concentrated suspensions
up to a viscosity of 7,000
mPa·s. Product quality is assured
due to the DCF's single-pass filtration
concept, short residence times and
the elimination of gas contact. Higher
permeate flux means that a smaller
installed equipment footprint is required.

This system can be adapted to
count tablets or gummy products
The DMC Series is an automatic tablet/
capsule counting machine (photo) that
can be equipped with special parts
and devices and modified to become
a counter for gummy products. By
replacing the hopper and tray for the
gummy, it is possible to count and fill
both conventional tablets and gummy
products with a single counting machine.
The adaptable gummy-exclusive
tray features an embossed stainlesssteel
surface to improve the flowability
Continuous casting for
membranes, films and more
This company offers continuous filmcasting
systems (photo, p. 57) for
the production of membranes, separators,
ceramic tapes and optical
films. The systems use a stainlesssteel
belt to transport a layer of liquid
product through a series of carefully
controlled sections. This involves
heat and mass transfer in the evaporation
process or a controlled phaseseparation
process in a precipitation
section. Once these processes have
