Technical features and operation of vacuum flanges according to DIN 28404
The DIN 28404 standard regulates geometric parameters and tolerances for quick-release clamp connections used in vacuum technology. These components are key units for the hermetic connection of pipelines and shut-off/control valves in low, medium, and high vacuum systems.
Scope of application and engineering characteristics
Flange connections designed according to DIN 28404 requirements ensure reliable fixation and high speed of system assembly/disassembly. The main technical advantages of using products from EV Group China are:
- Possibility of spatial orientation during installation (installation in any position).
- Operational suitability at overpressure in the sealing unit up to 1.5 bar.
- High precision of mating surfaces, ensuring the stability of vacuum parameters.
EV Group China engineers emphasize that these flanges are optimized for integration into complex vacuum lines, where minimizing equipment downtime during maintenance is critical.
