ACS Multi-Port Rotary Valve in 3D
What this video shows
The ACS Multi-Port animation shows how two, three or four rotary-airlock compartments in one housing can discharge to independent conveying lines, split feeds or one common downstream conveyor.
What the footage shows
The animation moves through three operating arrangements: separate ports feeding independent pneumatic conveying lines, ports sharing a larger discharge path, and several compartments feeding one common conveyor.
It also shows that each airlock compartment has its own rotor and drive, so one section can stop while the remaining sections continue to discharge material.
Process challenge
A long outlet under a large bin or collector can create a difficult interface between storage and conveying.
One elongated rotor concentrates capacity, maintenance access and failure risk in a single machine, while several independent valves require more housings, transitions and installation space.
Demonstrated solution
ACS combines two, three or four standard rotor sections in one extended housing.
The provider describes 12 × 24, 12 × 36 and 12 × 48 inch opening areas, with independent drives and separated airlock compartments that can feed one or several downstream systems.

About this video
How the Multi-Port arrangement works
Operating principle: Bulk material falls from the vessel above into several rotary-airlock compartments arranged across one extended inlet.
Each rotor divides the incoming solids into pockets and carries them from the inlet to its assigned outlet while limiting the gas exchange across that section of the valve.
The compartments share a housing concept, but they are not one continuous rotor.
That distinction matters because independent shafts and drives allow the ports to operate against different material demand or maintenance conditions.
What changes between the three shown configurations
Independent feeds: A port can discharge into its own pneumatic conveying line, allowing a wide source vessel to supply several smaller transport systems.
Split duty: Selected ports can run while others remain stopped, provided the vessel outlet and material distribution above the valve keep the active compartments supplied without creating stagnant zones.
Common discharge: Several ports can feed one elongated adapter or conveyor when the downstream equipment is designed for the combined solids rate and the air introduced or displaced by every section.
The animation makes these layouts easy to compare, but it does not establish which arrangement will work for a specific powder.
Engineering checks before selecting a multi-port valve
Material distribution: The vessel geometry must deliver reasonably uniform loading across the long inlet, otherwise one compartment can starve while another floods.
Check bulk density, flowability, particle size, cohesion, abrasiveness, moisture, temperature and the tendency to bridge or segregate across the outlet.
Pressure boundary: Define the pressure differential across every port, expected air leakage, displacement air and the effect of leakage on pocket filling.
A rotary airlock is a controlled-clearance machine, not a gas-tight shut-off valve.
Controls: Independent drives need a clear start, stop and interlock philosophy tied to downstream availability, high level, overload and upstream isolation.
A stopped compartment can keep the rest of the assembly available, but only if the common process around it can tolerate the changed flow distribution.
Maintenance: Confirm access to each motor, gearbox, bearing, seal and rotor section, plus a safe method for isolation and removal.
The compact plan view is useful only when technicians can still reach the parts that wear.
Where this video fits in a selection study
Use the animation to decide whether the process needs one common discharge, several independent lines or a hybrid arrangement.
Then develop a duty sheet using the rotary valve selection and sizing guide, compare the pressure-boundary role on the Rotary Valves technology page, and review the published ACS Valves company profile.
The final selection still requires current model documentation, material data, expected throughput, leakage criteria, hazard review and measurable acceptance conditions for the actual installation.
