8251-046 Woodward diesel generator set actuator governor module

The Woodward 8251-046 electro-hydraulic actuator is a key component designed by Woodward for high-precision prime mover control.

As a member of the EG-3P series, the core function of the 8251-046 is to precisely convert the current control signal from the electric governor into a proportional mechanical rotational position. This output shaft connects directly to the fuel, steam, or gas control mechanism of the prime mover, enabling precise control of speed, load, or power through fine adjustment of the supply.

This actuator, with its powerful hydraulic torque and extremely high control precision, can operate stably and reliably in harsh industrial environments. The Woodward 8251-046 is not only suitable for constant speed control of generator sets but also widely used in various industrial applications requiring precise speed or power regulation. Its superior performance makes it an ideal choice for ensuring the safe, efficient, and stable operation of systems.

Features:

The 8251-046 is hydraulically driven, with a maximum torque output of 20 ft-lbs (27.1 N-m). This powerful output capability allows it to easily drive fuel control linkages in large engines or turbines, overcoming mechanical resistance and ensuring rapid and precise control action.

The actuator's proportional control characteristics mean that its output shaft position is linearly related to the input current signal. This provides a solid foundation for high-precision speed control and load sharing, enabling rapid response to load changes and minimizing speed fluctuations.

The 8251-046 integrates seamlessly with various Woodward electric governors, forming a complete and highly reliable speed control system. This system-level compatibility simplifies design and commissioning and ensures optimized overall control performance.

Its robust cast iron housing and internal component design allow the 8251-046 to withstand harsh environments such as vibration, high temperatures, and oil contamination.

The MS3102A-20-27P connector used further enhances the reliability of electrical connections with its excellent moisture-proof, dust-proof and shock-resistant performance, thereby ensuring the stable performance of the actuator during long-term operation.
