Pneumatic Conveying

Dense and dilute phase pneumatic conveying systems for powder and granular materials.

Protecting Pellet Quality at Rotary and Diverter Valves

October 13, 2026 by DYPNF
DYPNF rotary valve with drive, rotor pockets visible at the inlet flange

How pellets are trapped or struck at rotary and diverter valves, which points to review when selecting them, and why valve design alone does not settle pellet…
