Rupture disc ODV - For low to medium pressures

 

ODV is primarily used for applications with low to medium pressures, e.g. for gases, liquids and applications with two-phase flows. The disc has a standard operating ratio of max. 80 %*. For burst pressures of less than 1 barg, ODV can be installed directly between flanges or angular rings.

*Depending on the specific application

ODV has a three-layer design:
The burst element is located on the side facing away from  the process to protect it against corrosive media. The breaking points are cut into the burst element using lasers and define the burst pressure with outstanding precision. The sealing element prevents gases from escaping in normal operation.  The vacuum support, as the name suggests, enables ODV to  be used in processes with a vacuum.

Rupture disc / bursting disc ODV
REMBE® forward acting rupture disc ODV

Your advantages

  • Suitable for use even with full vacuum due to integrated vacuum support.
  • Minimum fragmentation during opening.

The challenge of the ODV rupture disc is to ensure an optimal combination of three layers. Even the tiniest inaccuracy will mess up the quality of the product. But practice makes perfect, and after so many years at REMBE® the whole procedure runs like a clockwork.
