Roto-Disc, Inc. Airlock/Double-Dump Valve Assemblies

Roto-Disc® Airlock/Double-Dump valves are the solution for processing dry or slurry material into or out of pressure or vacuum environments. Intermediate accumulator chambers are designed for ledge-free flow of material from valve to valve. Cycle-timing and pressure equalization
couplings are available for turn-key feeding solutions. These are the perfect replacement for leaky rotary-vane valves or other, flimsy double-dump valves.

In Comparison

Rotary valves have a gap between the blade ends and the housing that allow leakage. The constant scraping of material between the blade and housing causes even hardened surfaces to wear-out.

Double-Dump Concept/Capabilities

This Roto-Disc® valve design takes double-dump valves to the next level. Our double-dump assemblies can be used to process material into/out of differential pressure environments by timing, weight or volume. This is a revolutionary processing solution that can take the place of other feeding devices and make your process more efficient!

Don’t waste time and money programming what we’ve already programmed

The Roto-Disc® Cycle Controller (RDCC)™ allows you to easily control your double-dump assembly to get the throughput you want. Purpose-driven programs, all with manual override, may be saved for specific recipes/batch sizes.
