VALVE CHEMICAL COMPATIBILITY CHART 3

1 VALVE CHEMICAL COMPATIBILITY CHART 3. GUIDE TO COLOUR CODING: Exceptional COMPATIBILITY . Satisfactory to good COMPATIBILITY with insignificant effect, minimal marking or corrosion. Poor COMPATIBILITY with moderate effect, possibly softening and swelling, loss of strength - not recommended. Not recommended for any use. No information. POLYPROPYLENE. CARBON STEEL. PVDF (KYNAR ).

Final selection of material should be dictated by the specific environmental requirements. Factors such as:- temperature, VALVE type, pressure, flow conditions, other trim components, VALVE brand, etc., can all have significant effect on material selection hence this is only a rough guide. Furthermore, recommendations vary between manufacturers. Results are based on an exposure period of 48-hrs and any exposure beyond this period may produce alternate outcomes.
