Dyna Plus Actuators (Formerly Barber-Colman)

DYNA Plus actuators (formerly Barber-Colman) now manufactured to original OEM Specifications by QCC can be operated with Woodward controllers to provide an engine governor for speed and power control of piston and gas turbine engines or steam and water turbines. The actuators can also be used in remote positioning and load control systems.

Actuators have output work capacities of 1, 4, 6 and 8 ft-Ibs. No special requirements are needed for mounting the DYNA actuator on the engine. It can be located at any convenient position since there are no requirements for a mechanical drive or oil connections. DYNA 8 actuators’ through output shaft allows clockwise and counterclockwise shaft rotation.

Standard features of all DYNA actuators include:

  • All-electric
  • All engine compatibility
  • Mounts in any position
  • Engine mounted
  • High reliability due to few moving parts
  • Proportional actuator
  • No hydraulic or oil line
  • No special maintenance
  • Spring returns output shaft to minimum position
  • Precise repeatability
