8262-959 | Woodward | High-Torque Engine Control Actuator

Product Description

The 8262-959 from Woodward is an electronically driven actuator engineered to translate low-level control signals from electronic governors into precise mechanical movement of fuel racks or throttle valves.
Designed for continuous duty on medium- and high-speed engines, this unit delivers stable positioning, rapid transient response, and consistent torque output under demanding operating conditions.

The actuator integrates seamlessly with Woodward electronic governor systems and is optimized for applications requiring accurate speed regulation, smooth load sharing, and dependable fuel control across varying loads and ambient environments.

Key Technical Characteristics

The 8262-959 is built around a high-efficiency electromagnetic drive and hardened mechanical output stage, enabling reliable performance in vibration-intensive installations.

Core attributes include high stall torque for direct fuel rack actuation, closed-loop position control for repeatable accuracy, and fast step response suitable for parallel generator operation. The housing and internal components are selected to tolerate extended exposure to heat, mechanical shock, and industrial contaminants.

FAQ

Is this actuator suitable for both diesel and gas engines?
Yes. It is designed to control fuel delivery mechanisms on both diesel fuel racks and gas throttle valves when paired with compatible governors.

Can it be used in parallel generator operation?
Yes. The fast dynamic response and stable positioning make it suitable for load sharing and isochronous speed control applications.

Does it require external position feedback devices?
No. Position sensing is integrated within the actuator assembly for closed-loop control with Woodward governors.
