Product Overview

The Woodward EGB-13P (Part Number: 8240-381) is a high-performance proportional electro-hydraulic actuator used for precise engine speed and load regulation. It converts electrical control signals into mechanical shaft positions to adjust fuel racks or steam valves. This actuator is crucial in power generation, marine propulsion, and industrial engine systems, ensuring efficient combustion and stable governing.

Technical Specifications

Engineering Advantages

• Proportional Response Accuracy: The actuator provides linear mechanical output in response to electrical input, ensuring precise frequency control and preventing overshoot or hunting during load fluctuations.

• High-Torque Hydraulic Power: Despite its compact size, it delivers 13 lb-ft (18 Nm) of torque, overcoming friction and spring forces in large fuel injection pumps or steam valves.

• Extreme Thermal Resilience: The unit is designed to operate across a wide temperature range, from -40°C to +85°C, ensuring reliable performance in both cold start and high-heat environments.

• Simplified Mechanical Integration: The compact dimensions (200 mm x 150 mm x 50 mm) allow easy installation in tight spaces, while the standardized mounting orientation simplifies retrofitting in marine and industrial setups.

• Integrated Hydraulic Feedback: Internal hydraulic pressure helps dampen mechanical oscillations, protecting the fuel rack from erratic movement caused by engine vibrations or electrical noise.

FAQs

Is this Woodward EGB-13P actuator a brand new unit?

Yes, we supply only 100% brand new and original Woodward 8240-381 actuators in factory-sealed packaging to ensure full hydraulic integrity and long-term service life.

What type of oil does the EGB-13P require?

It typically uses the same lubricating oil as the engine it controls. Ensure the oil meets Woodward’s cleanliness specifications to prevent internal valve issues.

How do I calibrate the 20–160 mA input signal?

Technicians use a Woodward-compatible electronic governor to scale the output. The actuator should reach its minimum stop at 20 mA and maximum fuel position at 160 mA. Minor mechanical adjustments may be required to finalize the stroke.

Can this unit replace a standard mechanical governor?

Yes, the EGB-13P serves as a modern upgrade for older mechanical governors. When paired with an electronic control unit (ECU), it provides superior speed stability and load-sharing capabilities.
