GROUP 11 QUARTER-TURN ROTARY ACTUATORS

Model 11-160: Quarter-Turn Direct-Mount Valve Actuator

The Harold Beck Model 11-160 is designed for direct mounting to quarter-turn ball, plug, and butterfly valves, providing a compact and highly accurate automation solution. By eliminating external linkages, the 11-160 reduces installation footprint and positioning lag, ensuring more precise control of flow and pressure. Featuring Beck’s unique no-burnout motor, this actuator supports 100% continuous modulation without the risk of thermal failure, making it the ideal choice for demanding industrial valve applications.


Encased in a dust-tight, weatherproof NEMA 4X housing, the Model 11-160 protects its precision spur gear train and digital electronics from moisture and corrosion. The actuator includes a contactless position sensor for accurate, maintenance-free feedback and an electric handswitch for local operation during commissioning. With its rugged construction and advanced diagnostic capabilities, the 11-160 offers the reliability and performance required to optimize automated valve assemblies in chemical, wastewater, and energy facilities.


Direct-Mount Performance and Control Features:

  • • Direct-mount design for compact, accurate quarter-turn valve automation.
  • • Continuous duty motor technology ensures 100% modulation without burnout.
  • • Non-coasting motor and zero-backlash gearing for absolute positioning.
  • • Maintenance-free gear train and contactless position sensor for long-life service.
  • • Weatherproof NEMA 4X aluminum housing for superior environmental protection.
  • • Digital diagnostics and isolated signal feedback for seamless control integration.
