Actuators

At Alberta Governor, our selection of actuators comes exclusively from Woodward. Woodward products are known for their high quality and durability. We are the only Woodward Authorized Independent Service Facility in our region, and are equipped to service actuators onsite or do service calls.

We currently carry the following actuators:

Woodward Dyna 2000 & 2500

DYNA 2000 and DYNA 2500 linear actuators provide precise positioning with a minimal number of moving parts. Many of the moving parts normally associated with electric actuators are eliminated, prolonging the mean time between failure.

These DYNA actuators are suitable for installation on diesel, gasoline, or natural gas engines with fuel system force requirements of less than 13 pounds (58 N) of force. When paired with a Woodward controller, precise isochronous speed control of 5 to 30 HP engines (DYNA 2000) and 5 to 60 HP engines (DYNA 2500) is achieved.

Features include:

  • All electric
  • Fast response
  • Small & compact
  • Two moving parts
  • Spring return to minimum fuel
  • Mounts in any position
  • Precise repeatability
  • Meets INR & EMP for moderate tactical battlefield environment

Typical applications:

Woodward Dyna 7000 Rotary Actuator

The 70 degrees of rotation and compact size of the APECS DYNA 7000 actuator make mounting and interfacing with a variety of fuel systems a snap. This compact rotary actuator can be used on gasoline, natural gas, and diesel engines. On carbureted and throttle body applications, a direct connection between actuator shaft and butterfly shaft is possible, thus eliminating external linkage.

The DYNA 7000 delivers 0.169 N-m (0.12 lb-ft) with a 70° travel range. The actuator is ideally suited for use on genset sets, pump sets, and off-road vehicles used in construction, forestry, and agriculture.

The actuators have a self-contained oil sump, so a separate oil supply is not required.

The UG actuator produces 20 J (15 ft-lb) of work over 42 degrees of rotary output.

The UG40 actuator produces 85 J (63 ft-lb) of work over 38 degrees of rotary output.

Features include:

Woodward EG-3P, EG-6P, EG-10P

Used to control the flow of fuel or other energy source to a prime mover, EG-3P/6P/10P actuators convert an electrical signal to position a proportional rotary output shaft. These hydro-mechanical actuators provide the muscle for a Woodward 2301A, 723PLUS, or similar integrating electric control system.

EG actuators are suitable for controlling diesel and gas engines or steam and industrial or commercial gas turbines that drive alternators, DC generators, pumps, compressors, machinery, or locomotives. A Woodward hydraulic amplifier can provide larger work capacities. These actuators are also recommended for applications involving unattended starts. EG actuators can also be used for installations where prime movers operate in tandem to drive a common load. With two actuators connected in series, only one electric control is required to supply a common signal to each prime mover’s actuator.
