GROUP 22 ROTARY DAMPER DRIVES

Model 22-309: High-Torque Industrial Rotary Actuator

The Harold Beck Model 22-309 is a heavy-duty rotary actuator engineered to provide precise modulation for large dampers and heavy-load valve applications. Designed for 100% continuous duty, this high-torque drive eliminates the positioning drift and maintenance requirements of pneumatic alternatives. By utilizing Beck’s unique no-burnout motor technology, the 22-309 maintains absolute accuracy in high-cycle environments, ensuring your most critical process loops remain stable and efficient under maximum load conditions.


Housed in a ruggedized, weatherproof NEMA 4X enclosure, the Model 22-309 is built to withstand extreme industrial temperatures and corrosive atmospheres. The unit features a maintenance-free alloy steel gear train and patented contactless position sensing for wear-free feedback and long-term reliability. With integrated HART diagnostics and an electric handswitch for local operation, the 22-309 delivers the rugged durability and smart diagnostic intelligence required for high-uptime automation in power plants, steel mills, and refineries.


High-Torque Performance and Control Features:

  • • High-torque rotary output optimized for large-scale industrial dampers and valves.
  • • 100% continuous duty cycle motor prevents overheating during constant modulation.
  • • Maintenance-free gear train with integral self-locking mechanism to hold position.
  • • Contactless position sensor (CPS) ensures accurate feedback with zero mechanical wear.
  • • Weatherproof NEMA 4X housing designed for the harshest industrial environments.
  • • Advanced digital control module (DCM) for simple setup and health monitoring.
