Reverse Buckling Rupture Disk - RLS™

  • The RLS™ is a Precision Circular-Scored Reverse Buckling Rupture Disk (Bursting Disc)
  • When over-pressurized, this domed, solid metal, reverse buckling disk reverses and opens along a pre-weakened circular score line on the down-stream side of the disk.
  • A patented hinge welded to the disk facilitates relief opening along the score line and retains the disk’s central petal preventing fragmentation even at high burst pressures.
