Designed for use in safety relief valve isolation, primary pressure relief or in conjunction with a safety relief valve as secondary pressure relief, the Oseco PRO+KRGL non-fragmenting, reverse-buckling rupture disc has a best-in-class Kr value (used to determine the frictional flow loss through a rupture disc and holder) for improved flow and the use of smaller piping. The disc has a 95% operating ratio, allowing processes to operate near capacity without the disc bursting prematurely.fex0412ts21_inbody.jpg
