Microscored disks, for better resistance at all operating pressures

The primary characteristic of compression rupture discs (the Reverse Buckling models) is their ability to maintain curvature, and thus a stable performance, until inversion pressure is reached; this allows them to easily boast working pressure to inversion pressure ratios around 90%, even in the presence of counterpressures; these bursting discs are often also autosupporting against vacuum.

Such a profile makes DonadonSDD's Reverse Buckling rupture disks particularly suitable for the isolation of safety valves, both in the presence of liquids and in gas-only situation; their performance remains constant even after thousands of pressure cycles, making them a product of the highest versatility and reliability.
