Dump / flap valves (hot, abrasive, lumpy) in Steel Plants:
Crusher / screening dust collection (rotor-free where the dust is coarse)
Sinter-plant ESP — fine, wet, abrasive sinter dust where a rotor would jam; sinter-cooler hot sinter-dust discharge.
BF dust catcher — coarse / hot flue dust; cast-house dedusting — hot fume dust.
BOF hot ESP hoppers — where the collected fume dust is hot and lumpy.
Hot ESP hoppers across the plant (cross-cutting hot/abrasive points).
Ffinished steel — slabs, billets, coils — is solid product and needs no valves
