Serving Alberta & Western Canada with high-performance rotary airlock valves.
If you’re operating a pneumatic conveying or dust collection system across Alberta, a properly designed airlock rotary valve is essential for maintaining efficiency, controlling emissions, and ensuring safe operation.
Our airlock valves are engineered for reliable material handling in harsh Canadian industrial environments, from cement plants and grain facilities to food processing and chemical operations.
An airlock rotary valve (also called a rotary feeder) allows bulk material to pass between two areas of different pressure while maintaining an airtight seal.
This is critical in:
Without an effective airlock, systems suffer from air leakage, reduced efficiency, and potential safety risks.
We supply rotary airlock valves built to handle a wide range of materials and operating conditions:
| Material Type | Best For | Key Benefits |
|---|---|---|
| Cast Iron | General industrial use | Cost-effective, durable |
| Carbon Steel | Heavy-duty applications | High strength, longer lifespan |
| Stainless Steel (304/316) | Food, pharma, corrosive environments | Sanitary, corrosion-resistant |
| AR Steel / Coated Options | Abrasive materials | Extended wear life |
All units feature precision-machined housings and tight tolerances for optimal sealing.
The rotor (or vane assembly) is the core of valve performance.
Our design options include:
These features ensure minimal air leakage and consistent performance, even in continuous-duty systems.
Our rotary airlock valves are used throughout Calgary and Western Canada, including:
We understand the demands of cold climates, abrasive materials, and continuous operation.
For facilities handling combustible dust, compliance with NFPA 69 is critical.
Our valves can be configured for explosion isolation, featuring:
A properly specified airlock valve acts as a passive explosion barrier, helping protect your facility and personnel.
Handling abrasive materials like cement, sand, or minerals? Wear is unavoidable—but manageable.
We help extend valve life with:
As internal clearances increase due to wear, efficiency drops and NFPA compliance may be compromised—routine inspection is essential.
