Special valves & tank safety systems

Hygienic vacuum valves are used to secure lines in processing plants against impermissibly occurring vacuums (e.g. after sterilization).

Pipeline connection
The pipeline connection is designed as a screw connection according to DIN 11851 by default. Other connection types such as welded end, clampable geometry or connections according to DIN 11864 are available upon request.

The valve is triggered using a pre-tensioned spring as soon as the pipe system has a certain negative pressure.
