Drive Train: Durable
and Efficient
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.
Mounting Versatility:
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.
Housing: Superior Protection with
Convenient Access to Components

individual compartments
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.
