GROUP 11 QUARTER-TURN ROTARY ACTUATORS

Model 11-360: High-Torque Quarter-Turn Direct-Mount Valve Actuator

The Harold Beck Model 11-360 provides high-torque, precision control for large quarter-turn ball, plug, and butterfly valves via a direct-mount connection. Engineered to eliminate the mechanical complexities of linkage assemblies, this heavy-duty rotary actuator ensures absolute positioning accuracy and instant responsiveness for large-scale flow control. Its continuous-duty motor is designed for constant modulation, allowing it to handle demanding process loops without overheating or the performance loss common in pneumatic alternatives.


Encased in a corrosion-resistant NEMA 4X aluminum housing, the Model 11-360 is built to withstand extreme temperatures and corrosive industrial atmospheres. The actuator includes a maintenance-free spur gear train and patented contactless position sensing technology for wear-free, reliable feedback. With integrated HART diagnostics and an electric handswitch for local operation, the 11-360 delivers the rugged durability and smart diagnostic intelligence required for high-uptime automation in power plants, refineries, and steel mills.


Direct-Mount Performance and Control Features:

  • • High-torque output optimized for large-scale direct-mount valve automation.
  • • Continuous duty no-burnout motor for precise, high-frequency modulation.
  • • Direct-mount design reduces footprint and eliminates linkage hysteresis.
  • • Maintenance-free gearing and contactless sensor for long-life industrial service.
  • • NEMA 4X rated aluminum housing ensures protection in harsh environments.
  • • Advanced digital control module for intuitive diagnostics and field calibration.
