Hygienic vacuum valves are used to secure lines in
processing plants against impermissibly occurring
vacuums (e.g. after sterilization). The valve is triggered using a pre-tensioned spring as soon as the
pipe system has a certain negative pressure.
Use
- tValves are designed for use in the food, dairy and t
t beverage, pharmaceutical, chemical, and cosmet tics industries
- tUsed as a pressure equalization fitting in hygienic
t processing plants
- tOperating temperatures up to +140°C (+284°F)
-t The valve is designed for direct attachment to the
t air pipelines

Design Characteristics
-t Available in nominal diameters 25–50
- tLow-maintenance, service-friendly, and
t hygienic design
- tThe components of the valve body are manut factured from stainless steel AISI 316L and meet
t all common hygiene standards
-t Customer-specific materials and surface finishes
