The company is built on generations of conveying knowledge.

Early in our company history, ACS Valves manufactured entire pneumatic conveying systems. We decided to specialize in rotary valves, designing our products with a comprehensive knowledge of what goes on above and below the valve.

The company is owned and operated by two generations of the Thompson family.

Founded by CEO Tom Thompson, ACS Valves is led jointly with his son and daughter, co-COO and Presidents Greg and Megan Thompson. What they do is more than just a day job – it’s their personal mission to help each customer succeed.

Big Picture Approach : With our conveying system expertise, we design valves to boost the overall performance of your line.
Bulk Material Knowledge : No two ingredients are the same. Your valve is designed to optimize performance for your material and application.
Quick Turnaround : Because we care about making your job easier, we work hard to deliver fast quotes, shipments, and technical support.

The Facilities

With headquarters in southern Ontario, ACS Valves ships reliably throughout North America.

We cast rotary valve housings locally and CNC-machine parts in-house, allowing us to ship orders faster. We’re fully equipped to design, build, and inspect valves to the highest quality standards.

We even have an in-house test centre, where we can emulate application-specific conditions to help specify the best rotary valve for your material.

Longer Lifespans
Cast using 65% US steel, our valves have longer maintenance cycles, less seal leakage, and more precise tolerances.

Standardized Safety
When you need OSHA and NFPA compliance features, they are built into the valve design. We don’t charge you extra.

Reliable Shipping
To reduce downtime, we are bonded to provide fast shipping throughout the U.S. and Canada. No delays, duties, or brokerage fees.
