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
