Rupture Disks
Type S-90™ / DN25 (1″) – DN1000 (40″), BS&B™

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 SRB-7RS-TR™ is required.


Burst pressure range: 1.4 barg (20 psi) – 69 barg (1000 psi)

Other: Customised design
