Products advantages

KUB® has a two layer design: The smooth, unblemished surface of the sealing membrane faces the process. The buckling pin element, which defines the burst pressure, faces away from the process so it does not come into contact with the medium.This is particularly useful with corrosive media. It guarantees that the rupture disc functions perfectly, prevents premature response and increases the service life of KUB®.

KUB® is not only extremely easy to install – it is also simple to remove and reinstall. In addition to a standard operating pressure ratio of up to 98 %*, the design is robust enough to cope with incorrect handling before and during installation.

n  KUB® is the most rugged rupture disc currently available.

n  Extremely robust design ensures a very long service life –for fewer production standstills.

n  No rupture disc fatigue, even at high operating ratios.

n  Broad range of pressures and nominal sizes possible, also ideal for pure liquid applications.

n  Available in a wide range of materials and sizes

n  Simple to install without damage: the torque required for the flange connection is independent of the type of rupture disc used.
