SI2 safety valves
A full-lift spring-loaded safety valve, TÜV approved. Protects tanks against excessive pressure.
REF · SAFETY
Tanks always within limits
SI2 prevents the allowable pressure from being exceeded by more than 10%. It closes when pressure falls by max. 10% (gases) or 20% (liquids).
- For liquids and gases.
- Beverages, food, pharma.
