We must emphasize that valve disributors should not be regarded as experts in metallurgy,
plastic materials or chemicals. The tables are only intended as a guide in the selection
of body and trim materials to handle corrosive media.
Only practical operating experience by the valve user of particular corrosive media can be
considered a reliable guide. For new processes or new chemical compounds it is recommended
that pilot tests under operating conditions or laboratory tests should be carried out.
Factors which radically influence the performance of valve materials in practice would
- the inherent design and performance characteristics of the
- the process
- changes in the concentration of the fluid. For instance
start-up concentration may be much higher
or lower than when the process is fully on stream.
- temperature and pressure
