OsecoElfab launches the technically advanced LoKr reverse rupture disk for chemical process and petrochemical plants. The new disk design delivers a best-in-class Flow Resistance Factor, or KR, to maximize pressure relieving performance while delivering superior reliability and extraordinary service life.
The LoKr represents the next generation of design and engineering in pressure relief technology. The disk's architecture has been refined and optimized to improve performance in three key areas: keeping pressure drops in relief lines to an absolute minimum, providing maximum reliability and accuracy, and being suitable for the widest range of pressures, temperatures, and line sizes possible.
The reverse-buckling disk combines a dimple on the disk with an innovative knuckle on the holder to offer full-bore opening with exceptionally accurate burst ratings. This enables a higher flow rate on burst than previously possible, demonstrated by the disk’s low KR value of 0.22. This makes it easier to keep pressure drops across the relief line below 3%, when the LoKr is used in relief valve isolation. Process plants can continue to use smaller piping diameters with no loss of performance or efficiency, even at low flow rates.
Product Manager Hunter Franks: “After extensive research, design and testing, we are confident we have developed the highest performing reverse buckling rupture disk in the market. The LoKr offers superior reliability, a wider size range, a lower KR, and improved safety compared to other designs currently available.”
Steve Gallo, President of OsecoElfab: “The launch of the LoKr rupture disk is the latest example of how OsecoElfab places the customer at the center of all that we do. We have worked closely with existing customers to ensure the LoKr meets their current needs, and we will continue to support them with future challenges. As we strive to better serve our global customer base, the market can expect to see more innovations from OsecoElfab in the months and years ahead.”
Designed to ASME XIII standards and certified with a UD stamp at a best-in-class KR value of 0.22, the LoKr is available now.
