Drive Train: Durable
Beck’s durable gear train maintains accurate, consistent control element positioning even under the demanding conditions of an active control loop.
- Gear trains employ a unique, all spur gear construction of heat-treated alloy steels and ductile iron.
- Efficient, wide-face spur gearing virtually eliminates wear-induced backlash and positioning inaccuracies.
- Durable design provides up to 4 days of protection against intermittent or extended accidental stalls.
- Integral self-locking mechanism ensures that drives hold a load with the motor de-energized.
Manual Handwheel: Convenient
Manual Control Without Declutch
An easy-to-turn, spoke-free Handwheel is incorporated into the Group 75 design to allow manual operation during installation or power outages.
- Move valves and dampers to any position smoothly and easily without power, even under full load conditions.
- Mechanical stops in housing prevent manual overtravel.
- The motor operates at 72 or 120 RPM, so the Handwheel poses no safety hazard.
Mount in any Orientation for Greater Installation Flexibility
Beck Group 75 Actuators may be mounted in any orientation for greater installation flexibility.
Beck actuators are configured and lubricated in such a way that they may be mounted in any convenient position. This flexibility allows actuators to be installed in hard-to-fit locations.
As long as housing compartments remain accessible, there are no mounting orientation limts.

Beck drives feature a cast aluminum body with individual compartments to protect components from moisture and dirt, and allow easy access for installation and calibration.
- Precision-machined aluminum alloy castings with corrosion-resistant polyurethane paint provide a rugged, dust-tight, weatherproof enclosure designed to meet Type 4X standards. Models approved for use in hazardous classified locations are available.
- Individual compartments protect all major components: Motor, DCM, CPS, gear train and installation wiring terminal board.
- Each compartment can be accessed without exposing other components.
- Gasketed, precision-machined covers provide extra protection for harsh indoor and outdoor environments.
- Output and Handwheel shafts are also sealed with weatherproof, double-lip seals.
