常见问题

Why is EPDM the preferred material for starch slurry seal rings?

EPDM offers excellent resistance to starch enzymes, hot water, and cleaning chemicals while maintaining flexibility across temperature variations common in food processing.

How often should starch slurry valve seal rings be replaced?

Typically every 6-12 months depending on operating cycles, but inspect quarterly for wear, compression set, or surface degradation.

Can these seal rings handle abrasive starch particles?

Yes, the specified EPDM formulation includes additives for abrasion resistance, but proper filtration upstream is recommended to extend service life.
