Airlock/Double-Dump Valves


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.


Double-dump assemblies can be used to process material into/out of differential pressure environments by:

  • timing
  • weight
  • volume
