The ZOOK Z-VAC and Z-POS Series are a range of bi-directional rupture disk and holder assemblies designed to relieve between 1” – 109” (25 mm to 2768.6 mm) water column in one direction and 2 psig – 150 psig (0.14 barg to 10.34 barg) in the other direction uniquely protecting processing,
fermentation, storage tanks and low strength vessels from vacuum implosion or over-pressure failure in a single device.
Rupture Disk Features
● Highly accurate, ultra-low burst pressures starting at 1” (25 mm) water column
● Dual-acting design, with laser cut metal top section and girdle (when ordered in 316SS)
● Sizes 2” to 12” / 50 mm to 300 mm
● Standard 316SS girdle for full range of vacuum pressures ensures clean opening of seal at specified pressure
● Burst ratings from 1” (25 mm) of water column to 150 psig (10.34 barg)
● Temperature ratings to 500˚F (260˚C)
● Permanently attached 3D stainless steel tag shows positive and vacuum flow directions
● Optional integral burst indication
