Reverse Buckling Rupture Disk - S-90™

  • The compression loaded S-90™ Rupture Disk (Bursting Disc) offers an extended service life under pressure cycling conditions compared to a conventional tension loaded disk.
  • The S-90™ Rupture Disk (Bursting Disc) exhibits excellent fatigue resistance in cyclic pressure service, surviving 1,000,000 pressure cycles from 0-90% of its marked burst pressure.
  • The S-90 is a domed, solid metal, precision scored reverse buckling disk, which, upon over-pressure, reverses and opens along pre-weakened cross-score lines to provide a full relief opening.
