Flat metal bursting disks
Series SF
Types SF-M / SF-MV / SF-MD
Flat metal bursting disks for direct installation between flanges – without holder also for retrofitting in your existing systems. The multi-part (created by several positions) bursting disks are used to secure mainly low and static overpressure and/or underpressure.
Models
| SF-M | STRIKO – Flat, Multi-part |
| SF-MV | STRIKO – Flat, Multi-part, Vacuum resistant |
| SF-MD | STRIKO – Flat, Multi-part, Double effective (different pressures in over/under pressure direction) |
Advantages in the application
- used with or without holder
- can be delivered with different burst pressures in overpressure and underpressure direction
- upon request vacuum resistant with integrated vacuum support
- insensitive design with simple handling
- working ratio: 80% by use of special materials
- torque insensitive
- equipped with a 3D name-plate for safe detection of correct direction of installation as a standard
- suitable for gasses, vapours and liquids
