1-30 inches W.C.
• POSITIVE BURST PRESSURE RANGE
4 psig to 100 psig
• TEMPERATURE RANGE
-25° to 400° f

The VAPRO-S rupture disc is used in sanitary applications requiring extremely low vacuum relief: as low as 1" W.C. (vacuum relief) and up to 150 psig (positive pressure relief).
The VAPRO-S will rupture and achieve maximum flow area at
or below the maximum specified pressure. (note: Specified
pressure plus 6" W.C. equals maximum specified pressure.)
These discs may be supplied with perforated, composite-style
controlling membranes, fluoropolymer seal and a fluoropolymer or 316 Stainless Steel girdle.
