Safety Valves Vacuum Valve, Type VV

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.

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.
