VAPRO Rupture Disc

Brand: OsecoElfab
Add Product to My Catalog

The Oseco VAPRO is an economical alternative for applications requiring both positive and vacuum pressure protection. 

The VAPRO (Vacuum relief) operates over a range of 6” W.C.

The VAPRO rupture disc is used in applications requiring extremely low vacuum relief: as low as 1” W.C. (vacuum relief) and up to 150 psig (positive pressure relief).

The VAPRO will rupture and achieve maximum flow area at or below the maximum specified pressure. (Specified pressure plus 6” W.C. equals maximum specified pressure.)

The disc may be supplied with perforated, composite-style controlling membranes, Fluoropolymer seal and a Fluoropolymer or 316 Stainless Steel girdle.
