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 talk a lot about how easy it is to clean our valves. Watch as we put our dinner into one of our valves and then clean it up!

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

When conveying sticky material, you can get the benefits of a blow-through without the premature wear.

Reduce agglomerated lumps without degrading the material or creating excessive dust.

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

Cleaning is the worst! Make it better. Watch this video to learn how.

Complex in design but simple to operate, this glamorous valve model has some serious performance to back it up.

A feeder valve for sticky and abrasive materials combines pressurized air with the dry bulk material.

Enables quick, tool-less access to the rotor and the interior of the housing for cleaning.

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

ACS Valves Quick Clean Feeder on Rails is designed for quick take apart applications.

This valve can be taken apart, cleaned and reassembled in just minutes hassle free!

The Quick Clean feeder is easy to disassemble and reassemble, in as little as 2 minutes.
