Roto-Disc® Co. manufactures heavy-duty industrial valves for tough dry material and slurry applications. The valves will slice through almost any sticky, gummy or abrasive substance and won’t leak, gum-up or pinch/break product, even in high pressure (150psi) or high temperature applications.

Almost anything that runs through a process line can run through these workhorse valves.

Typical applications include mixer inlet & discharge, reactor fill and discharge, refill of loss-in-weight feeders, dilute and dense-phase pneumatic conveying, bulk-bag fill and discharge, hopper shut-off.
