Precise Fuel Control • Stable Speed • Rugged Performance

Our Electric Rotary Actuator is engineered for diesel generator engines to deliver fast, accurate, and reliable control of the fuel system. When paired with an electronic speed controller, it forms a complete governing system that maintains stable engine RPM under all load conditions—eliminating overspeed, underspeed, hunting, and frequency fluctuations.

The actuator converts electronic control signals into precise mechanical movement, ensuring that the generator responds smoothly and consistently to changes in load.

Key Functions

• Converts electrical control signals into mechanical movement
• Regulates fuel supply to maintain constant engine RPM
• Provides fast response during sudden load variations
• Ensures stable frequency and smooth generator operation

Typical Features

• High torque output for accurate positioning of the fuel rack or throttle lever
• Durable construction suited for continuous genset operation
• Low power consumption for efficient performance
• Compatible with standard electronic governors (such as ESD series)
• Reliable performance even in harsh industrial environments

Additional Technical Highlights

Proportional Rotary Movement

Enables smooth and precise control of engine fuel delivery across the operating range.

Rugged Metal Enclosure

Built to withstand vibration, dust, and engine-room temperatures.

Simple Electrical Interface

Two-wire connection for quick integration and easy installation.

Adjustable Control Arm

Multi-slot lever design allows flexible linkage configurations to suit various engine types.

Safe and Consistent Operation

Strong holding torque and rapid actuation help prevent overspeed conditions and ensure steady generator output.

Applications

• Diesel generator sets (prime and standby)
• Industrial diesel engines
• Marine engines
• Engines requiring precise electronic fuel control

Installation Flexibility

The actuator can be mounted directly on the engine, on a pump bracket, or inside a control panel. It supports horizontal or vertical mounting.

If moisture, mist, or condensation is present, vertical mounting ensures that water drains away from the unit, maximizing reliability and service life.
