ODV is primarily used for applications with low to medium pressures, e.g. for liquids, gases, and applications with two-phase flows. The disc has a standard operating ratio of max. 80 % (Depending on the specific application). In applicatins with burst pressures of less than 1 barg, ODV can be installed directly between flanges or angular rings.
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 escaping of gases in normal operation. The vacuum support enables ODV to be used in processes with a vacuum.
