Reverse Acting Metal Bursting Disks
Series SU
Types SU-R / SU-C / SU-X
STRIKO reverse acting metal bursting disks are installed in a standard holder SHU or in a pre-torqued holder SHU Pro between flanges. They are especially suitable for securing pulsating working pressures of medium to high strength.
Models
- SU-R
- STRIKO – reverse acting, shearRing
- SU-C
- STRIKO – reverse acting, C-form scored
- SU-X
- STRIKO – reverse acting, x-form scored
Advantages in the application
- fragment-free opening behaviour
- ideal as single pressure relief unit or used in combination with safety valve
- Vacuum resistant
- optimum working ratio: 90%
- counter pressures up to min 1.4 times of the burst pressure are possible
- testing safety valves without time consuming removal
- high pressure change resistance
- equipped with a 3D name-plate for safe detection of correct direction of installation as a standard
- ideal for securing media that tend to “cake”
Design options include integrated burst indication, standard materials and special materials. Ask us for advice on your application.
