The Group 11 series is the industrial standard for precise control of dampers, valves, and other final control elements via linkage connections. Built for continuous modulation without the duty-cycle limitations of standard actuators, these units ensure stable, hunt-free performance. From the 11-150 to the 11-430, Group 11 provides the rugged reliability and accuracy needed to optimize combustion and process efficiency.

Streamline your installation with Group 11 direct-mount actuators, engineered specifically for quarter-turn ball, plug, and butterfly valves. By eliminating external linkages, these actuators provide a compact, high-precision solution for automated valve assemblies. Models ranging from 11-160 to 11-460 deliver maintenance-free operation and exceptional positioning accuracy for the most demanding flow control environments.

Designed for space-constrained applications, the Group 31 compact rotary actuator is the ideal choice for small quarter-turn ball and butterfly valves. Despite its smaller footprint, it maintains the same rigorous standards for reliability and modulation precision as larger Beck models. It’s a versatile, cost-effective solution for automating smaller valves in diverse process industries where performance cannot be compromised.

When your application demands maximum power, the Group 22 series delivers high-torque performance for large dampers and heavy-duty valve control. These actuators are designed to handle high-load requirements without sacrificing precision or responsiveness. Models 22-309, 22-409, and 22-809 provide the robust construction and advanced control electronics necessary to manage large-scale industrial equipment with absolute confidence.

The Harold Beck Group 75 is a high-precision, compact rotary actuator designed for windbox dampers and quarter-turn valve automation in space-constrained environments. Engineered with 100% continuous-duty, no-burnout motor technology, it provides maintenance-free modulation and zero-backlash positioning that outperforms pneumatic drives. This NEMA 4X rated actuator includes high-temperature options and instantaneous response timing, ensuring absolute control and improved combustion efficiency in demanding industrial thermal applications.

The Harold Beck Group 57 is a Class I, Division 1 explosion-proof actuator designed for critical quarter-turn valve automation in hazardous oil, gas, and chemical environments. Featuring integrated on-board fail-safe backup power, these AC/DC-compatible drives guarantee emergency valve positioning during power loss without the complexity of pneumatic systems. The Group 57 combines high-precision modulation with a flame-proof housing and HART diagnostics, delivering 100% duty cycle reliability and maintenance-free safety in volatile atmospheres.
