Sampling valves BioCheck Combi

The RIEGER BioCheck combination valve is an aseptic sampling valve that is connected to a CIP/SIP valve without dead space.

With the BioCheck sampling valve, samples can be taken easily and safely from closed systems such as containers and pipes.
When designing this sterile fitting, particular emphasis was placed on the aseptic but also very compact design, so that it can be integrated into both sterile and CIP/SIP circuits without any problems and, above all, without contamination.

BioCheck sampling valves are certified according to TA-Luft / VDI 2440 / VDI 3479

All enclosures are also available with only 1 outlet.
Weld ends are the standard design for all housing types, but other connections are available on request.
