MECHANICAL FEATURES – Group 14 Linear Valve Actuators

One-Step Travel Adjustment


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.



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.

Gear Train


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.
