Tension type rupture discs are oriented in a system with the process media pressure against the concave side of the rupture disc. As the process pressure increases beyond the allowable operating pressure the tensile strength of the material is reached and rupture occurs.

Reverse Acting rupture discs are oriented in a system with the process media pressure against the convex side of the disc, placing the rupture 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.
