1: Valve type
2: TÜV number – Safety valve • Year of component inspection – Inspection No.
3: Seat seal material
4: Narrowest cross-section of flow
5: Co-efficient for steam/gases at 5% opening pressure differential,
Performance in the case of air (S/G = Steam/Gas)
6: Lift
7: Co-efficient for liquids at 10% opening pressure differential,
Performance in the case of water (L = liquids)
8: Setting pressure
9: Minimum / maximum application temperature
10: Serial number, e.g. 281711195
11: Data matrix code (serial number)
We check the safety valves for pressure resistance and tightness, adjust the requested
set pressure and seal them.
The identification on the type plate or on the spring bonnet of the valve is applied using
a permanent marking system. The identification also contains the necessary details
according to DIN EN ISO 4126-1.
