This is intended as a guide to the chemical resistance of material used in the manufacture of valves.
Many factors influence the corrosion rating and have to be taken into account. Those factors include temperature, aeration of fluids, concentration of fluids, velocity of stream, and abrasions in the fluid stream. The physical properties of material are affected differently by each corrosive media. The internal moving parts should have an "A" rating as these moving parts are in direct contact with the media.
In some cases, a "B" rating can be given to body material in direct contact with media, when the corrosion rate is not one to cause any serious problem.
Ratings Explanation(based on media at room tempearture-unless otherwise noted) These ratings are only a guideline based on industry experience. Neither IndustrialMartUSA, nor any of it's employees, are responsible for any problems arising from use of this data.
