Forward Acting Metal Bursting Disks
Series SZ
Types SZ-X / SZ-M / SZ-MV
Forward acting metal bursting disks are installed in a standard holder SHZ or in a pre-torqued holder SHZ Pro between flanges.
Especially suitable for securing medium to high working pressures.
Models
- SZ-X
- STRIKO – forward acting, x-form scored
- SZ-M
- STRIKO – forward acting, Multi-part (layer) design
- SZ-MV
- STRIKO – forward acting, Multi-part, Vacuum resistant
Advantages in the application
- fragment-free opening behaviour
- ideal as single pressure relief unit or used in combination with safety valve
- high working ratio: up to 90%
- “Fail-Safe” design – incorrect installation leads to bursting of the SZ-X at or underneath the actual burst pressure
- also obtainable with a PTFE-liner
- equipped with a 3D name-plate for safe detection of correct direction of installation as a standard
- suitable for gasses, vapours and liquids
Design options include vacuum-resistant construction, a PTFE liner and special materials. Ask us for advice on your application.
