Reverse acting rupture disc KUB® V

metal

Engineered to last: Robust, high performance, rupture disc solution. The KUB® is the only rupture disc to be manufactured using Euler's critical load formula to determine the burst pressure, creating the most robust, high-performance rupture disc available. Unlike other rupture disc solutions where a weak point is created in the metal, the KUB® is a unique, highly engineered solution, benefiting from a series of buckling pins which accurately collapse for reliable, full bore, opening. As there is no specific weak point on the rupture disc, the KUB® is an extremely robust solution, almost immune to damage by incorrect handling, improper installation or even being dropped! This maximises the lifespan of the disc and minimises long-term investment by lowering ongoing replacement costs. The KUB® features a two-layer design, with the smooth, unblemished surface of the sealing membrane facing the process minimising the possibility of damage due to corrosion. The KUB® V rupture disc protects safety valves against corrosive solids or adhesive media and is installed upstream of the safety valve inlet. It is certified to resist a back pressure of 135 %* of the defined burst pressure and thus enables you to test safety valves in-situ without having to remove the valve for servicing. Advantages -Longer service life and service intervals for the safety valve due to isolation of the valve from the process. -Reduction in safety valve maintenance costs and the amount of production downtime required by in-situ tests. -You can use safety valves manufactured from lower cost materials because they are isolated from the process medium during normal operation.
