Forward Acting Metal Rupture Disc
Forward acting metal rupture disc are installed in a standard holder SHZ or in a pre-torqued holder SHZ Pro between flanges. They are especially suitable for securing medium to high working pressures.
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
