Pressure & temperature ratings
The following pressure, temperature and pH limits
refer to equipment without sightglass. For
information on limiting conditions for the individual
components refer to the respective installation &
operating manuals.
The lowest or highest limit of any component
determines the decisive overall limiting conditions of
the equipment.

Fluids with pH value above 7 have the potential to cause glass corrosion. As the temperature and pH
value of the fluid increases, the possibility of etching the glass also increases.
