A Technical Framework Built on Field Data, Not Catalog Assumptions
Most airlock valve specifications are sized from generic catalog charts that cannot account for the variables that actually determine performance: bulk density variation, particle morphology, moisture content, and pressure differential interaction. This guide gives engineers and plant managers the framework to match the right Prater series to their process conditions, plus the data to validate that decision internally.
What the Guide Covers
Six focused sections that take you from process conditions to a validated airlock specification.
Decision Logic
A structured series-selection table matching your process requirements to the right Prater airlock platform.
The Physics of Reliability
Why velocity is the enemy of longevity, and how Prater's 8-blade large-pocket design reaches throughput targets at 10 to 12 RPM instead of 25 to 30.
Design Trade-Offs
Source management versus reactive venting, and how self-adjusting packing glands eliminate a chronic maintenance failure point.
Performance Benchmarks
Prater engineered standards versus typical industry offerings across four key design dimensions.
Technical Center Validation
How to eliminate commissioning risk by testing your exact material before equipment ships.
Engineer's Checklist
Four questions to answer before finalizing any airlock specification.
Built on a Century of Application Engineering
Prater Industries has engineered rotary airlock valves since 1925. A century of field experience across food processing, chemical handling, mineral processing, agricultural applications, and industrial dust collection means our specifications are built on empirical data, not theoretical sizing charts.
- Field data from thousands of installed valves
- Real-material testing before equipment ships
- Series matched to your exact process conditions
Every recommendation in this guide is validated at the Prater Technical Center using real materials under real production conditions.
