Description
The Woodward 8256-079 is a specialized actuator within the 1724 series, uniquely engineered for applications requiring high-precision control through integrated sealed position feedback. This model is designed to provide the control system with real-time data regarding the exact position of the actuator shaft, allowing for superior closed-loop accuracy in demanding environments. Whether integrated into complex power management systems or critical industrial engine setups, this actuator ensures the precise fuel modulation required for stable, efficient operation.
As a highly capable Woodward 8256-079 unit, its design prioritizes durability and feedback integrity. The “sealed” aspect of the position feedback protects the internal sensing components from environmental contaminants, making it an ideal choice for heavy-duty applications where external debris or moisture might otherwise compromise mechanical sensor reliability.

Frequently Asked Questions
⚙️ Why is the 26-degree travel limit so important? The 26-degree range is the optimized mechanical arc for this actuator. Operating within this specific window ensures that the internal electromagnetic forces are balanced, providing the most linear and responsive control over the fuel linkage. Pushing beyond these limits can cause mechanical binding or erratic positioning behavior.
🔌 What is the advantage of sealed position feedback? In industrial settings, dust, oil, and moisture can infiltrate standard sensors, leading to signal drift or failure. The “sealed” design ensures that the feedback loop remains consistent over the lifespan of the unit, reducing the need for frequent recalibration and preventing unexpected system downtime.
⚠️ Why is it crucial to keep the actuator shaft perpendicular? Maintaining a perpendicular orientation relative to the fuel linkage reduces side-loading on the actuator shaft bearings. If the shaft is misaligned, the increased friction can lead to premature mechanical wear, sluggish response times, and an increased risk of the actuator “hunting” as it tries to overcome the resistance to move.
🛠️ How do I verify the installation alignment? Use a protractor or a precision square during initial mounting to ensure the actuator shaft is aligned correctly with the linkage arm at the mid-point of its travel. The goal is to minimize the angular change across the entire 26-degree stroke, which optimizes the force transfer from the actuator to the fuel rack.
