Type S-90™, BS&B™: DN 25 (1in) – DN 1000 (40in)

The S-90™ Rupture disk is a domed, full-metal reverse buckling cross scored rupture disk. When the bursting pressure is reached, the rupture disk reverses and opens without fragmentation along the indentation, releasing the full relief cross-section. Safety head/Bursting disc holder type S90-7R™ or SRB-7RS™ or SRI-7RS-TR™ is required.
