The mechanical characteristics of the FPM and FFPM seals subjected to an ambient temperature below –5°C require the implementation of
proper insulation on the valves equipped with such seals. Contact us for more information.

The chemical resistance of the valve is subject to the type of fluid, the temperature, the pressure, as well as the materials and
seals of the valve.
Please contact us to have a personalized analysis of the resistance of one of our products to a given fluid
You can also consult, for information only, the table given in ISO 10358. However, this table cannot be considered as a
recommendation by SAFI who could not be held liable for the use of this document.
Our valves are guaranteed for an average fluid velocity in the pipeline of ≤ 2 m/s. Please contact us with the working conditions for any higher
speed.
