Model 22-309
Rotary Damper Actuator |
Beck electric actuator products
have earned a reputation in the process industries for precision,
reliability, and low maintenance
durability over decades of service.
Customers use Beck electric
actuator products for a vast array
of applications to meet their
process control needs. Several of
the more commonly equipped
applications are listed below with
Beck electric actuator product
selections for your reference.
Dampers
Beck rotary damper drives and
damper actuators are utilized on a
multitude of damper applications
to improve process control.
Common applications include
louvers, butterflies, and radial
inlet vanes on ID fans, FD fans,
primary air, windboxes, overfire
air, coal mills, and many other control dampers.
The Group 11 product line is often found on low to medium torque
applications (20 lb-ft to 5,200 lb-ft). Group 22 products are utilized for
high torque applications (3,000 lb-ft to 8,000 lb-ft), and Group 31 compact rotary actuators are utilized on low torque applications (15 lb-ft
to 30 lb-ft).
Industrial Valves

Control loop performance is only
as good as the performance of the
control valve. It is a well-documented
fact that many
industrial control loops function
poorly as a result of valve
actuation problems. Beck valve
actuators eliminate the problems
caused by both pneumatic and
typical electric actuators, and
maximize potential of control
systems.
Group 11 Quarter-Turn
Rotary Actuators are
suitable for most rotary valve
applications. For smaller valves
with low torque requirements,
Group 31 Compact Valve Actuators may be more suited for your application. Rotary valve applications
include almost any ball valves, butterfly valves, and plug valves.
The Group 29 and Group 14 Linear Valve actuators are a great fit for
most globe valve applications. These units can be mounted in any
orientation and provide superior performance in the harshest conditions.
Burner Tilts
For modulating large dynamic loads such as multiple burner tilt arrays,
Beck Group 11 drives provide up to 5,200 lb-ft of torque. Exceptionally
stable, Beck drives provide repeatable positioning control for maximum
boiler efficiency. The most common rotary actuator models utilized for
these applications are model 11-400 and model 11-430.
Burner Air Registers
Beck’s Group 42 drives are designed to meet the actuation needs of long
stroke linear applications. Typical applications include burner air
registers and OFA port dampers, but they can be used on any
application requiring up to 18 inches of linear stroke. Employing Beck’s
unique design characteristics, reliability and quality into a long stroke
linear actuator design fills a much requested slot in the Beck family of
products. Like all Beck drives, the Group 42 is designed for simple
installation, no duty cycle limitations, excellent performance and little or no required maintenance.
Fluid Drives / Variable Speed Couplings

Fluid Coupling equipped with
Model 11-200
|
Beck Group 11 drives are ideal for
use with variable speed fluid
drives and variable speed
couplings on pumps and fans.
They provide exceptional stability
and repeatability under live loads.
These features deliver the precise
positioning ability essential for
optimum performance. You can
contact Beck for assistance in
selecting the appropriate drive for
your application or download the
bulletin for basic drive sizing
charts.
Industrial Steam Boilers
Whether a boiler is large or small, subject to severe load swings or
base-loaded, Beck drives provide the best possible valve and damper
control. The consistent and efficient control over time helps to meet
emissions regulations, reduce costs, and avoid costly trips and outages.
Weather, dust, dirt, and temperature conditions (-40 to 185 F on most
drives) do not affect performance.
Damper applications utilize Group 11 and Group 22 drives for louvers, butterflies, and radial
inlet vanes on ID fans, FD fans,
primary air, windboxes, overfire
air, coal mills, and many other control dampers.
Valve Applications utilize Group 11 Quarter-Turn Rotary Actuators for
many rotary applications and Group 29 or Group 14 for linear valve
actuation.
 Gate Dampers
A multi-revolution Group 11 drive is available for those applications
in which a gravity-type gate must
be raised or lowered in response
to signal changes. Often used to
regulate differential pressure by
controlling balancing dampers on
the hot exhaust side of furnaces,
Beck drives provide high accuracy
and quick response even when
continuously modulating. This
results in greater fuel economy
and longer refractory life. Contact
the factory for additional details
on our multi-revolution products.
