How our conveying system knowledge benefits your line

At ACS Valves, we manufacture rotary valves. No surprises there. What you might not know is that for a number of years, we used to manufacture entire pneumatic conveying systems.

Eventually, we decided to narrow our focus down to valves, because (a) we make them well, (b) we realized, as the most important piece in the system, having the right valve is crucial for system performance, and (c) other manufacturers could benefit from our valve R&D. The switch to specialised manufacturing has been rewarding.

But we haven’t forgotten our history. To the contrary, we continue to embrace it.

We actively retain our knowledge of conveying systems because we know it makes our valves better, which makes your lines better.


1) Valve performance relies, at least in part, on integrating well with the rest of the line equipment. You can’t just pull a valve off the shelf and assume it will perform the way you want it to. This is why we always ask what kind of line you have before we make a valve recommendation.

At the end of the day, the valve is one component in a larger system, and if it doesn’t play nice, it becomes a hunk of metal—no matter how nice the valve is.

2) If something goes awry, our system knowledge makes us way more helpful to you. We can help you troubleshoot issues with the valve, as well as how it works with the equipment above and/or below it.

3) For custom conveying systems, a standard valve often won’t cut it. As engineers, we can help you design and manufacture the right valve that integrates a specialized system.

4) We know what issues to look for, which is why we factory-test each valve in an actual conveying system. This serves as assurance for our customers—not just that it’s a solid rotary valve, but that we have checked to make sure it performs in a real environment—as a component—before it’s shipped out.

5) The experience we gained from decades of making conveying systems (and helping customers with their challenges) lead to the valve innovations we’re now known for.

  • RotorRails came after understanding how much maintenance people hate cleaning heavy, time-consuming valves.
  • The sleeve-style, Teflon® shaft seal was developed when customers talked about needing to prevent contamination and clean-up from leaks
  • When sustainability started becoming more important to manufacturers, we found ways to reduce the energy needed to power the valve.

The list goes on. Combined, these valve developments have added up to a more productive line, while reducing downtime, leaks, maintenance and safety hazards.

The bottom line?

Everything we know about valves, and everything we develop to improve them is because we were (and, at heart, still are) systems people.

Yes, we want to continually improve our valves. But that’s because we want to help optimize your entire line.
