K-Tron Aerolock™ Brand Airlock Rotary Valves Overview

We are continually upgrading and refining our airlocks, which now include more than 160 models and sizes. This broad scope and variety of Aerolock sizes and models enables K-Tron to provide the most appropriate airlocks and rotary valves for applications in the milling and baking, food, pharmaceutical, plastics and chemical process industries.

Each Aerolock rotary valve is handbuilt to exacting tolerances and is performance tested. If an Aerolock rotary valve fails the performance test, even by the smallest of margins, we don’t ship it.

Aerolock Airlock Rotary Valve materials of construction and coatings

Standard materials of construction include cast iron or stainless steel housings and end plates with carbon steel or stainless steel rotors. They can be coated with chrome, Teflon^®, tungsten carbide, or a material of your specification for greater wear resistance. The rotor can be equipped with flat or relieved tips, open-ended, hubbed, reduced displacement or staggered pockets, to name a few.

Wide range of rotary valve sizes

Aerolocks are available in round or square inlet/outlet configurations providing 80 mm through 500 mm [3 in through 20 in] openings. Displacements range from 0.25 to 230 dm³ / Rev [0.009 to 8.12 ft³ / Rev]. Selecting the right size at the correct speed can yield any throughput desired up to over 100 tons per hour.
