TYPICAL APPLICATIONS
Beck control drives are ideally suited for use on
ball, plug and butterfly valves, as well as dampers
and fluid drives. When equipped with a sheave
and multi-turn option (consult your Beck Sales
Engineer for details), the drive can be used to raise
and lower a weight-balanced damper.
DCM-2 equipped Beck drives are designed for
precise position control in modulating applications.
The drive is best utilized when its full travel is
employed to achieve its greatest sensitivity and
resolution, although the driven device may operate
through a considerably smaller range. Beck drives
can be configured with special linkage to deliver
greater torque where needed, so that drive size
and resultant cost can be minimized.
Valves can be furnished by Beck as unitized
assemblies with control drives mounted and
tested in the factory. Depending on the valve
and application, valves can be mounted directly
or using a bracket and linkage. Also, drives may
be installed in the field with mounting hardware
furnished by Beck or the customer. Drives for
dampers are generally installed at the site on a
mounting platform separate from the damper.
BECK LINKAGE KITS
Beck hex and pipe linkage kits are available
for completing the mechanical connection from the
drive crank arm to the load. Through the use of a
standardized selection, the linkage can be ordered
even if the exact length is not determined until the
drive and driven device are installed.
All Beck foot-mounted drives are furnished
with a crank arm and rod end (see pages 8, 10
and 13 for dimensions). All rod ends furnished
by Beck incorporate bearings to accommodate
some lateral misalignment. Once the connection
is made, linkage kits can be adjusted ±1 1/2”
(38 mm) without removal of the crank arm or load
lever, making final mechanical calibration simple.
