BioCheck SamplingValves
RIEGER
Incorrect sampling may produce wrong or inaccurate results
especially in sterile processing which may lead to rejection
of whole production lots. With the BioCheck sampling
valve range, RIEGER offers relief.
The BioCheck sampling valve was engineered for a sterile
processing environment and takes simply and reliably samples
from vessels and pipes. The valve has a very compact
construction which makes it easy to integrate it into sterile
processes and CIP/SIP circles, contamination-proof.
BioCheck valves have no dead spaces and
can be completely cleaned. A PTFE bellow
provides a hermetic seal against the environment.
The valve body is made from
stainless steel 1.4404 (AISI 316L) and the
surfaces in contact with product have a
quality of Ra <0.8 μm as standard. Higher
grade materials such as AL6XN or Hastelloy
as well as higher surface qualities, e.g.
0.4 μm and electro-polished quality are
available optionally.

The valves can be operated
manually, by a
pneumatic actuator
or in a combined
arrangement.
The valve is
available in a tank
or pipe version
with TriClamp,
Ingold or Neum o
BioControl connection.
RIEGER
can also supply
special connections.
RIEGER has been
supplying BioCheck
series valves for
the past 15 years. In
2010 the valves received
3-A approval and since
With the BioCheck valve (the photo shows the Compact version)
one can take samples from closed systems like vessels or pipes
in a simple and safe way (photo: RIEGER)
shortly, the new Compact version is also available with
EHEDG certificate. Here, jiggering protection, a lockable
hand wheel and connections to NEUMO and AWH standards
were realised. BioCheck valves are built from DN 6 measure.
All types equipped with a flask can be used for a perfectly
hermetically closed sampling process. Optional accessories
are connections to a mobile steam boiler, fast connection
systems and tight-shutting casings for up to 10 bar pressure
(BioShut).
RIEGER has delivered hundreds of aseptic BioCheck mini
valves for sampling during milk collection on trucks. The referenced
list features impressive names such as Friesland-
Campina and Zott.
A certificate of German TA-Luft regulation issued by TÜV
SÜD confirms that all BioCheck valves fulfil the specifications
for leakage proof according to guideline VDI 2440/VDI 3479.
