The Oseco VAPRO and POSIPRO are economical alternatives for applications requiring both positive and vacuum pressure protection. The VAPRO (vacuum relief) and the POSIPRO (positive pressure relief) operate over a range of 6" W.C.
The VAPRO rupture discs are 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 POSIPRO rupture discs are used in applications requiring extremely low positive pressure relief: as low as 1" W.C.
Both The VAPRO and POSIPRO 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.
