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 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.
