APECS DYNA Rotary Actuators
Electric actuation solutions for simple and reliable engine control
Woodward’s DYNA line of rotary actuators for engines offers many choices of torque ranges—from 0.066 N-m of the small GBA actuator to 7.3 N-m of the large DYNA 8400 actuator.
All DYNA actuators are unidirectional (electrically driven in one direction and spring returned in the opposite direction) and are available in clockwise and counterclockwise rotations.
Whatever your torque, travel, terminal connection, or mounting requirements, you’ll find a Woodward actuator to meet your needs. Or, we can custom design one for your exact specifications.
The DYNA 7000 rotary actuator supplies 70 degrees of rotation in a compact package. The actuator is suitable for 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. Learn More
GBA (Golf Ball Actuator)
The GBA is a laminated, rotary actuator for use on diesel, gasoline, propane, and natural gas engines. Sized at roughly the diameter of a golf ball, the GBA is suitable for power generation (stationary and mobile gensets) and industrial equipment applications.Learn More
DYNA 8000 Series
Woodward DYNA 8000, 8200 and 8400 rotary actuators are robust and reliable. Paired with a Woodward controller, they ensure precise isochronous or droop speed control of medium-sized engines depending on the type of fuel system used. Applications include speed and power control of piston and gas turbine engines or steam and water turbines. Learn More
DYNA 70025 (For Stanadyne Fuel Injection Pumps)
Designed in collaboration with Stanadyne, these rotary actuators are integrated onto the pump cover of Stanadyne "D" Series injection pumps, eliminating replacement of internal parts or addition of external linkage. Installation is done simply by removing the existing cover and replacing it with the new cover. Used on Stanadyne injection pump models DB / JDB / DC / DB2 / DB4 / DM2 / DM4. Learn More
DYNA Plus Series
DYNA Plus actuators can be operated with any of the DYNA controllers to provide an engine governor for speed and power control of piston and gas turbine engines or steam and water turbines. The actuator is equipped with a non-contact feedback transducer, making it useful in positioning systems. Learn More
