rupture disc KUB® V - For isolating safety valves

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.

*Depending on the specific application

Rupture disc / bursting disc KUB in combination with safety valve
KUB® V: Reliable protection of safety valves against corrosive media

Your 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.
  • Leak-tight design prevents emissions.
