Overview
The Woodward 9905-658TM-25LP Linear Actuator is part of the TM-25LP series, engineered for high-force, low-displacement applications in turbine and engine control systems. It provides 1 inch (25 mm) of linear movement, ideal for operating fuel metering and steam control valves that require proportional positioning.
This actuator combines electric and hydraulic technologies to deliver reliable retracting motion with minimal hysteresis. Moreover, it integrates seamlessly with Woodward control platforms such as MicroNet and Atlas, supporting closed-loop control and real-time feedback. Its rugged, compact design allows installation in space-constrained environments and ensures long-term durability under vibration, temperature extremes, and contamination.
Therefore, the 9905-658TM-25LP is widely used in power generation, marine propulsion, and industrial process control systems where precise valve actuation is critical.

Typical Applications
-
Steam and Gas Turbines: Positions fuel and steam control valves with high precision and repeatability.
-
Power Generation Systems: Used in turbine governor systems for load control and ramping.
-
Marine Propulsion: Controls engine fuel delivery in shipboard power systems.
-
Industrial Process Control: Actuates valves in chemical, refining, and water treatment facilities.
-
Retrofit Projects: Replaces legacy actuators in older turbine installations with modern control compatibility.
For instance, in a steam turbine, the actuator retracts to adjust steam flow based on load demand, ensuring stable operation and efficient energy conversion. In addition, its electric-hydraulic design minimizes response time and improves control accuracy.
