NOTE: - that this table is intended as a general guide only and does not imply guarantee of service performance. 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.

NOTE: - that this table is intended as a general guide only and does not imply guarantee of service performance. 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.
