Overview Introduction
Rotary Valve BT
The Blow-Through (BT) AerolockTM configuration enhances rotor cleanout and enables installation in tight spaces. It is frequently used in applications involving sticky materials to prevent material buildup in the rotor pockets. The BT is engineered for heavy-duty industrial use, handling applications with pressure differentials of up to 0.8 bar(g) [12 psi(g)] and temperatures as high as 107.2°C [225°F].

The Blow-Through (BT) AerolockTM configuration enhances rotor cleanout and enables installation in tight spaces. It is frequently used in applications involving sticky materials to prevent material buildup in the rotor pockets. The BT is engineered for heavy-duty industrial use, handling applications with pressure differentials of up to 0.8 bar(g) [12 psi(g)] and temperatures as high as 107.2°C [225°F].
The BT features eight blades that maintain a minimum two-blade labyrinth seal to minimize air leakage. The rotors are equipped with relieved tips for materials that tend to form skins or thin sheets on end plates and the housing, while non-relieved tips are used for cereal products. Additionally, the BT incorporates two tapered roller bearings—one on the thrust side and one on the drive side.
