This manual contains the information needed
to install, operate and maintain Beck model
75-106, -105 & -103 compact rotary actuators,
manufactured by Harold Beck & Sons, Inc. of
Newtown, Pennsylvania.
The Group 75 actuator is ideal for the space-
restricted hot environments typical of boiler
windbox applications and other devices requiring
up to 80 lb-ft (108 N•m) of torque. It is also well-
suited to small rotary valve applications in tight
spaces.
Group 11 rotary actuators ...
provide precise position control
of dampers, quarter-turn
valves, fluid couplings, and
other devices requiring up to
1,800 lb-ft (2 440 N•m) actuator
torque.
Group 22 digital control
actuators ...
are designed for accurate,
reliable, modulating, digital
control of high torque
applications. The actuator
is ideal for use in large boiler
applications, such as ID/FD
fan dampers.
Group 29 linear valve
actuators ...
are ideally suited for
globe valves from 1” to
8” (25 mm to 203 mm)
diameter. Beck’s unique
“Tight-Seater™” coupling
provides positive seating
of valves.
Group 31 compact
rotary actuators ...
are particularly suited
for coupling to ball,
plug, and butterfly
valves up to 4”
(102 mm) diameter,
and small dampers.
IMPORTANT: This manual contains
information that will make installation
simple, ecient and trouble-free. Please
read and understand the appropriate
sections in this manual before attempting
to install or operate your actuator.

Limit Switches Two SPDT, one for CW and one for CCW limit of travel. Actuators
having position sensing capability (Options 6 & 5), have over-travel
limit switches set 1/2° outside the CW and CCW travel range (typically,
–0.5° and 100.5°). Actuators without position sensing (Option 3), have
end-of-travel limit switches set at the CW and CCW travel range
(typically, 0° and 100°).
Auxiliary Switches Up to four 3 A, 120 V ac switches available (.5 A @ 125 V dc, .25 A @
250 V dc).
See page 21 for switch setting diagram.
Handswitch Permits local electrical operation, independent of controller signal.
Standard on all units. An auxiliary contact is available as an option for
remote auto indication (rated 3 A at 120 V ac).
Handwheel Provides manual operation without electrical power.

SAFETY PRECAUTIONS
WARNING
Installation and service instructions
are for use by qualied personnel
only. To avoid injury and electric
shock, do not perform any servicing
other than that contained in this
manual. Please read and understand
the appropriate sections in this
manual before attempting to install
or operate your actuator.
STORAGE INFORMATION
Beck actuators should be stored in a clean, dry
area. Damage due to moisture while in storage is
not covered by warranty.
INSTALLATION—MECHANICAL
There are many considerations regarding
proper mechanical installation—see the
instructions beginning on page 11 for details. Refer
to the outline dimension drawings for physical
dimensions and required clearances.
VALVE ACTUATOR INSTALLATIONS
CAUTION
Working with valves installed in a
pipeline can be dangerous. Take
appropriate precautions when
mounting to installed valves.
INSTALLATION—ELECTRICAL
See the instructions beginning on page 14 for
details regarding electrical installation.
CAUTION
For maximum safety, the Beck
actuator body should be grounded.
Use the green grounding screw
in the wiring compartment of the
actuator.
CAUTION
Always close covers immediately
after installation or service to prevent
moisture or other foreign matter
from entering the actuator.
