The Vac-Saf® System Two-Way Pressure Relief (Vacuum and Overpressure)

The Vac-Saf™ family of products satisfies requirements for low burst ratings, typically under 15 psi (1 bar) and often in the range of a few inches of water column (millibar) for the protection of vessels and silos from vacuum collapse or the effects of light overpressure. Both industrial companion flange configurations and sanitary/aseptic connection versions of the Vac-Saf product range are available to provide either one-way or two-way (pressure and vacuum) relief.
