Tank Bottom Diaphragm Valve

Mounted at the lowest point of fermenter for broth discharge, tank draining and bottom CIP waste removal. Flush‑mounted dead‑zone‑free design prevents material buildup and microbial contamination; compatible with SIP / CIP processes.

Aseptic Sampling Valve

Mounted on fermenter side wall for sterile broth sampling during fermentation. Samples are taken for dissolved‑oxygen, pH and cell‑density testing. It prevents foreign bacterial ingress and avoids cross‑contamination of the entire tank batch.
