These pressures can be applied on use
of suitabble:
1. Gaskets
2. Bolts
3. Tensioning rings
In cases of maximum bolt threading length and
suitable gaskets at the process connection, the
float pressure specification applies

If the pressure specifications for the process connection (e.g. flange) and float differ, the lowest
pressure figure is then the nominal pressure
