ARCA Regler GmbH/Products/BIOVENT® Hygienic valve


  • Series 391
  • DN 15–150
  • PN 10–25

Thanks to its modular design, the BIOVENT® hygienic valve guarantees optimum adaptation to your system and combines freedom from dead space with perfect cleaning options. The hygienic design with extremely low maintenance and at the same time high efficiency and precision of the control valve ensures maximum cost-effectiveness with the lowest total costs of ownership. The hygiene design is well thought out down to the smallest detail. It is CIP-capable and  ensures that any residue is drained, so that cleaning problems, oxidation damage or carry-over during media change are ruled out. The FDA-compliant seals guarantee flush sealing with the housing wall.  The dynamic sealing of the valve stem with a special combination sealing element prevents the ingress of foreign bodies as well as damage to the stem and the bearing. The precision trims are optimized in terms of shape and material to meet your requirements. In addition to hygiene, BIOVENT® guarantees uncomplicated adaptation to changing operating conditions through an exchangeable control plug and the clamped valve seat.

This is what distinguishes BIOVENT® hygienic valves:

  • Powerful valve actuator
  • Wide variability in housing types and connections
  • Hygienic housing and stem sealing
  • Robust precision trims
