Woodward 8405-223 Electric Actuators And Drives

Applications

The Woodward 8405-223 Electric Actuators and Drives are designed for precision actuation and drive control in turbines, engines, and industrial machinery. Typical applications include:

• Electrically-driven valve and governor actuation in steam, gas, and hydraulic turbines.
• Industrial engines requiring precise position and speed control of mechanical components.
• Integration with Woodward digital or servo controllers for automated process and load regulation.
• Compact systems where limited space requires small-form-factor actuators and drives.
• Retrofitting older control systems with modern, high-precision electric actuation.

These actuators enable precise, repeatable motion while ensuring reliable performance in challenging industrial environments.
