RALX Series: 99% Sealing Efficiency with Graphite Sealing System

The RALX platform of rotary air locks achieves industry-leading 99% sealing efficiency through our proprietary Graphite Sealing System. This advanced sealing technology minimizes air leakage, reduces energy consumption, and prevents material degradation during pneumatic conveying operations. Our rotary valves feature precision-machined housings with adjustable rotor tips that maintain tight clearances even after extended operation in abrasive environments.

Available in multiple configurations including RALX-HD (Heavy Duty) for cement and mining, RALX-BT (Blow Through)for pneumatic conveying, RALX-HT (High Temperature) for hot gas applications up to 400°C, and RALX-SC (Side Channel) for specialized material handling. Each model is engineered with hardened rotor tips, Ni-Hard liners for abrasion resistance, and isolated bearing systems for extended service life.
