Group 14 Linear Valve Actuators
Electrical Features
Beck Drive Motor:
Precise, Reliable Control
Together with Beck’s control electronics and rugged gear train, Beck
motors provide the precise, reliable positioning required for modern
control loops.
 Never overheats or burns
out, even under demanding
modulating control or stalled
conditions.- Reaches full speed and
torque in less than 50
milliseconds and stops
within 25 milliseconds,
eliminating deadtime.
- Provides extremely accurate
positioning in modulating
applications.
- Will not coast or overshoot
the desired position.
- Low current draw of 0.16 A
to 3.0 A, and therefore low
power consumption,
eliminates the need for relays and permits the use of
uninterruptible power supplies.
- Maintenance-free with double-lipped, grease-sealed bearings.
 Electric Handswitch:
Time-Saving Local Operation
Valves may be operated at their
individual locations with the builtin
electric Handswitch. This saves
time during installation and
troubleshooting, allowing on-line
adjustments to be made quickly
and easily by bypassing the
electronics in the drive and
control system.
The Handswitch also serves as an
electrical backup in the event of
control system failure.
Auxiliary and Over-travel Limit Switches:
 Two over-travel limit switches and
up to four auxiliary switches are
provided on Beck drives.
- SPDT switches rated for a
minimum of 6 A at 120 V
ac, (three times maximum
motor current for most
models) to ensure long life.
- Field-adjustable to operate
at any point in the drive’s
travel range.
- May initiate secondary
functions or provide remote
indication of drive position.
- Eliminates unreliable and
maintenance- intensive
proximity switches.
