Overview Introduction
Rotary Valve MD
The Maximum-Duty (MD) AerolockTM is widely used with some of the most challenging materials, including minerals, chemicals, fillers, food ingredients, filled pellets, PVC compounds, and diatomaceous earth. Engineered for heavy-duty to severe industrial applications, the MD can handle pressure differentials of up to 1.4 bar(g) [20 psi(g)] and/or temperatures as high as 121°C [250°F]. Its exceptional ability to withstand extreme shock loads and elevated temperatures makes the MD Aerolock a "true maximum-duty" performer.

The Maximum-Duty (MD) AerolockTM is widely used with some of the most challenging materials, including minerals, chemicals, fillers, food ingredients, filled pellets, PVC compounds, and diatomaceous earth. Engineered for heavy-duty to severe industrial applications, the MD can handle pressure differentials of up to 1.4 bar(g) [20 psi(g)] and/or temperatures as high as 121°C [250°F]. Its exceptional ability to withstand extreme shock loads and elevated temperatures makes the MD Aerolock a "true maximum-duty" performer.
The MD features a ten-blade rotor that maintains a minimum three-blade labyrinth seal to minimize air leakage. The ten-blade rotor is available with either flat or relieved tips, offering several rotor options. Additionally, the MD incorporates two tapered roller bearings—one on the thrust side and one on the drive side.
