Sampling Valves BioCheck Classic

By means of the BioCheck sampling valve, samples can be taken easily and safely out of closed systems like vessels and pipings. When designing this sterile fitting, special emphasis was placed on the aseptic, but also very compact design, so that the integration can be carried out easily and especially free from contamination in both sterile and in CIP/SIP cycles.

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

All housings are also available with only 1 outlet.
For all housings welding ends are the standard version, other connections on request.
