Rotary Airlocks & Valves

Rotary airlocks and valves are critical components in bulk material handling and pneumatic conveying systems. They allow products to transfer smoothly from one chamber or vessel to another while maintaining a consistent air pressure and flow rate.

In applications where materials are gravity-fed, vacuum-conveyed, or pressure-fed for filtration, maintaining air and pressure balance is vital. A well-engineered rotary airlock helps to:

• Minimize air and pressure loss between connected systems
• Accurately meter and control product flow into conveying lines or downstream equipment
• Regulate feed rates for consistent process performance
• Act as a flame or explosion barrier, improving plant safety

Rotary airlocks help to improve production efficiency, reduce waste, and protect products from contamination or harsh processing conditions.

Rotolok designs and manufactures a full range of heavy-duty, NFPA-compliant, and USDA-approved rotary airlocks and valves for demanding industries – from food processing and plastics to cement, pharmaceuticals, and chemical applications. Each unit is precision-built to ensure reliable sealing, long service life, and easy maintenance.
