Designed for applications requiring either fully open/close positions or variable positioning, these gates handle dry products efficiently while preventing material from hanging up—thanks to their unobstructed orifice design.
Precision & Reliability in Every Cycle
At the heart of the Lorenz Roller Gate is a commitment to accuracy and longevity. The adjustable nylon cam rollers create a dust-tight seal on the blade, preventing leakage and contamination, even in demanding environments. The Lorenz Roller Gate ensures smooth product flow, and minimizes maintenance requirements. Whether in food processing, plastics, chemicals, grain, or milling operations, Lorenz Roller Gates deliver consistent, repeatable performance.
Built to Fit Your Application
Lorenz understands that every installation is unique. That’s why Regular or CEMA flange patterns are available, ensuring seamless integration into existing systems. Standard construction features aluminum housing with a polished stainless steel blade—lightweight yet durable for long service life. For more demanding or specialized applications, carbon steel or full stainless steel construction options are available.
Additional standard features include:
- Unobstructed orifice ensuring product does not hang up
- Positive Blade Lock (PBL) between blade and cylinder rod for secure positioning
- Internal magnetic piston for enhanced control
- Cushioned air cylinder to reduce mechanical stress
- Stainless steel blade for corrosion resistance and clean product contact
- Temperature rating up to 82º C (180º F) for versatility across industries
Dual Air Cylinder Roller Gate Options — our Roller Gate, re-engineered into a compact, twin-actuator design for smooth, balanced opening/closing in tight spaces.
Key Benefits:
Offers the flexibility of operating both gates independently or in sequence for optimized flow control
Ideal for Food & Pet Food, Grain, Milling, and Chemical Applications
Handles a wide range of material options — including fine powders, small to large granules, abrasive materials, and even sticky materials.
Maintains the same dust-tight, durable construction as single gates
