Description

The LoKr rupture disc's advanced design delivers a best-in-class Flow Resistance Factor (FRF), or KR value, to maximize pressure relieving performance while providing superior reliability and extraordinary service life.  

The disc's architecture has been refined and optimized to improve performance in three 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 dimple design supports full-bore opening with exceptionally accurate burst ratings to support operational efficiency, especially at low flow rates.
