Rotor tips wear down over time, causing issues with material flow. Our video illustrates why rotor maintenance is so critical to the overall efficiency of your rotary airlock valve.

It's easy to order a new valve from ACS and have it get to you. Here's how the process works from start to finish.

Need a guide to removing the drive side endplate on your ACST-4 seals? Watch a quick visual breakdown of the process. The video is silent.

Our valves will fit literally anywhere. Watch the video to find your industry.

Keep valves compliant by ensuring rotor-to-housing clearance stays below 0.0079.

Every material is different, so every valve has to be designed to handle each combustible dust in order to prevent deflagration.

We're facing our critics head on.

Learn the fundamentals of airlock performance, how to minimize air leakage and how improve efficiency.

Choosing the right rotary valve can improve your productivity. Choosing the wrong one can do the opposite.

Our test center is designed to test your materials to determine which airlock valve/feeder is best suited for your application.

This simple rotary valve re-assembly sequence shows the significant labor and downtime savings associated with this rotary valve design

Each rotary valve goes through a thorough inspection process before leaving ACS.

Production operations include CNC machining of rotor blades, rotor adjustable tips, slide-gate parts, inspection panels, and metering-s

ACST-4 Glandless Teflon Shaft Seal can be easily removed and reassembled in just a few minutes using basic hand tools.

Eliminates the need for conventional packing gland-style shaft seals.
