Description
Woodward SMM40
Technical Specifications
- Brand: Woodward
- Model: SMM40
- Product Type: Electro-Mechanical Servo Actuator
- Control Signal: Analog current or voltage command
Functional Features
- Precision Positioning: Provides highly accurate valve positioning with minimal deadband.
- High Dynamic Response: Capable of rapid movement to accommodate sudden load changes or emergency trips.
- Integrated Feedback: Contains internal position sensors for closed-loop control verification.
Application Scenarios
Widely used in gas turbine fuel control valves, steam turbine governing systems, and industrial engine throttle controls.
Performance Parameters
- Positioning Accuracy: Exceptional repeatability for stable process control.
- Force/Stroke: Optimized mechanical output for specific valve sizing.
Material Composition
Housed in a rugged, industrial-grade enclosure with precision-machined gears, high-efficiency motors, and durable bearings.
Structural Characteristics
Compact, cylindrical or rectangular profile with mechanical linkages, electrical connectors, and mounting flanges.
Working Principle
Receives a position command from the controller. The internal motor drives the output shaft, while the integrated feedback sensor continuously reports the actual position to the controller to correct any errors.
Installation Requirements
Mechanically link to the valve with precise alignment to prevent binding. Ensure electrical connections are secure and shielded.
Usage Precautions
Do not force the actuator past its mechanical stops. Verify the feedback calibration after any mechanical linkage adjustments.
