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
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.
