Reverse Acting rupture discs (bursting discs) are oriented in a system with the process media pressure against the convex side of the disc, placing therupture disc (bursting disc) in compression. As the burst pressure rating of the disc is reached, the compression loading on the rupture disc causes it to reverse, snapping through the neutral position and causing it to open by a predetermined scoring pattern or knife blade penetration.Reverse Buckling disks are recommended for combination with pressure relief valves to isolate them from normal process conditions ensuring excellent leak tightness, reduced valve maintenance expenses and often allowing the use lower cost valve trim.
