What is ProAct Woodward?
The Woodward ProAct is a high-performance electric actuator designed by Woodward, world leader in control systems for engines and turbines. Unlike hydraulic or pneumatic actuators, the ProAct is 100% electric, making it a modern, clean and precise solution for controlling control elements such as throttles, valves or intake flaps.
This advanced technology enables fine, reactive position control, ideal for gas engines, generator sets, thermal power plants, cogeneration plants or marine systems. Thanks to its closed-loop system, it constantly adjusts its position according to the controller’s instructions, guaranteeing optimum machine control.
Why use a ProAct Woodward actuator?
The ProAct Woodward converts a control signal into a highly precise mechanical movement. It is used to control the position of the air or fuel intake in an engine, directly influencing its speed, power and emissions.
On a gas engine, for example, the ProAct continuously adjusts the throttle opening to maintain a constant engine speed, even under varying load conditions. This role is crucial in power generation or propulsion applications, where stability and responsiveness are absolute requirements.
The advantages of ProAct Woodward over conventional actuators
Switching to a 100% electric actuator like the ProAct offers numerous operational advantages. Firstly, it eliminates the need for fluids (oil or compressed air), reducing the risk of leaks, maintenance requirements and the costs associated with ancillary infrastructure.
Secondly, the ProAct Woodward offers fast response times, high accuracy and excellent position stability, even in the presence of vibration or severe operating conditions. It is also easier to integrate into modern architectures, particularly with Woodward controllers such as the 723, 2301E or MicroNet models.
Finally, its robust design and compatibility with a wide range of supply voltages (24 VDC, 48 VDC) make it particularly adaptable. Integrated versions are also available, such as the ProAct ITB (Integrated Throttle Body), which combines the throttle body and actuator in a single unit, simplifying assembly and wiring.
Typical ProAct Woodward applications
ProAct is used in a wide range of industries, including:
- Power plants (generators, gas turbines)
- Industrial gas and biogas engines
- Cogeneration systems (CHP)
- Oil and gas installations
- Marine (propulsion or on-board production)
In all these cases, regulating speed, torque or combustion is a critical issue. The ProAct Woodward provides a reliable, modern solution that meets the latest performance and environmental requirements.
