From October 9th to 11th GEA Tuchenhagen has exhibited at BIOTECHNICA
2007 in Hannover/Germany.
We have presented our product range of VESTA sterile valves with all types
as well as the VESTA valve ring distribution system and our VARIPURE cleaning
technology.
VESTA sterile valves by GEA Tuchenhagen with EHEDG certification
The VESTA range of sterile valves by GEA Tuchenhagen – a new generation of
shut-off valves for sterile applications – has been specially developed for the
pharmaceutical, food, cosmetic and biotech markets. The valves heart is the
PTFE bellows which acts as a sealing element with a patented sealing system and
long service life.
Process reliability and maximum product quality are
known requirements of sterile applications. In particular, shut-off valves must
be reliable as they perform a key role in hermetically sealing the process
interior off against the external atmosphere. Shut-off valves also have to be
CIP/SIP cleanable.
Successful and reproducible cleaning is only possible -
if a ‘Cleaning in Place’ (CIP) procedure is used - if particular design
criteria are met. In addition to the quality (topography) of the surfaces in
contact with the product, the geometry, above all, has a decisive influence.
One of the significant development aims was to provide proof of
cleanability. Modern development tools – such as flow simulation – were used to
draw conclusions regarding the cleaning efficiency as early as possible in the
development stage.
The results of the EHEDG cleaning test of the VESTA
range of sterile valves proved to be more than satisfactory. All of the test
runs produced excellent cleaning results. An appropriate report – the
precondition for issuing an EHEDG certificate – is available.
The EHEDG
certification of the VESTA range of sterile valves means that the final
building block of the development – namely proof of cleanability – is now in
place. In achieving this level of certification, GEA Tuchenhagen has clearly
demonstrated to users that these products feature state-of-the-art technology
and cleanability.
VESTA sterile valves up to DN 65 available!
The VESTA range of sterile valves is now also available in larger nominal
widths. The extended range includes the following sizes:
- new - DN 32, 40, 50, 65 (DIN pipe class)
- new - 42.4, 48.3, 60.3, 76.1 (ISO pipe class)
- new - 1 ½ “, 2“, 2 ½ “ (OD pipe class)
This expansion of the range means that we are now able to offerusers complex
areas of application based on their sterile technicalrequirements, even for
larger flow volumes. The extended VESTA range of valves is designed for manual
operation, with NC/NO pneumatic actuators made from plastic and stainless steel
(can be equipped with T.VIS monitoring systems) and in various other housings.

details of the new nominal widths in our new brochure!
VESTA Multiport – innovative ring distribution system for complex
processing !
The valve ring distribution systems on VESTA sterile valves allow complex
processing using different operating, cleaning and sterilisation media.
Compared with conventional systems with single valves or complex and expensive
valve blocks, the single seat valves in the VESTA Multiport distribution system
are located
pocket-free in a ring with an appropriate annular passage cross
section.
The modular construction of the ring distribution system allows
the configuration to be changed to meet the individual task. A maximum of six
isolation valves can be located in both the inlet and return circuits. It is
also possible to have differing valve sizes in one ring. Moreover, the VESTA
Multiport allows different flow directions for the inlet and return pipework
with fixed grid spacings to be planned in advance.
VESTA Multiport systems
are designed to be pocket-free and CIP Compliant. They provide a total drainage
capability, can be located in the smallest of spaces, and at the same time set
new standards In terms of cost effectiveness.
New benefits for the plant designer:
- Minimisation of the costs for planning and installation
- Qualification and validation of the system in the production plant
- Reduction of the time required for planning, supply, installation and
commissioning
