BI-Directional Rupture Discs - The 2-in-1 rupture disc
The bi-directional acting rupture disc opens in one direction for a defined overpressure and in the other direction for vacuum. It is primarily used in storage tanks and processes involving gases or liquids. The rupture disc permits a standard operating ratio of 80 %* in the overpressure direction and 70 %* in the vacuum direction.
* Depending on the specific application
By combining the principles of the KUB® reverse acting rupture disc with the buckling pin and the three-section design of the ODV forward acting rupture disc, we can offer you a REMBE® rupture disc that responds at two different but precisely defined burst pressures.
- Performs the work of two rupture discs at one installation point.
- No additional holder required: mounted directly between flanges or angular rings.
- Suitable for a wide range of applications.
