Woodward 5466-409 Mechanical Hydraulic Governor (UG-40)
The Woodward 5466-409 is a specific model of the legendary UG (UG-40) series of mechanical hydraulic speed regulators from Woodward. It represents a classic design that has stood the test of time in governor technology and is renowned worldwide for its unparalleled simplicity, robustness and reliability. For decades, it has been the preferred control device for thousands of diesel engines, used in demanding industrial applications and providing stable performance even in the harshest environments.
For users who need a robust solution that can be “set and forgotten”, the 5466-409 is undoubtedly the benchmark.
Highlights of core products
1. Ultimate simplicity and reliability
◦ Pure mechanical hydraulic design: Does not rely on any electronic components, sensors or software. This means that it is completely unaffected by electromagnetic interference (EMI), radio frequency interference (RFI), or power failure, and is essentially explosion-proof.
◦ Durable and sturdy: All components are made of high-strength materials, capable of withstanding high temperatures, high vibrations and harsh environments, with an extremely long service life.
◦ Verified performance record: Since its inception, hundreds of thousands of UG governors have been reliably operating worldwide, and its design is recognized as a classic in industrial history.
2. Outstanding performance and adjustability
◦ Precise speed regulation: Sensitive and stable speed control is provided through precise flyweight and hydraulic systems, with steady-state speed regulation as low as 1% (adjustable), meeting the requirements of most industrial applications.
◦ Simple on-site adjustment: The speed setting value and speed adjustment (Droop) can be easily adjusted on-site through the external adjustment knob without the need for special tools or software.
◦ Strong driving capability: The hydraulic power cylinder provides a powerful output force, which can directly drive the fuel rack of large engines.
3. Low maintenance and long service life
◦ Simple design: The internal structure is intuitive and the maintenance technical requirements are low.
◦ Extensive spare parts support: As a classic product, there is an abundant supply of spare parts worldwide, and the maintenance cost is low.
Compatible with multiple fuel systems: It can be adapted to most engines with mechanical fuel injection pumps.
4. Suitable for special environments
It is an ideal choice for explosion-proof areas (such as mines, oil and gas fields), military equipment or extremely remote regions, where the reliability of electronic devices may be challenged or maintenance conditions are limited.
Typical application scenarios
• Generator set: A diesel generator set used for backup power supply and normal-load power generation, providing stable frequency control.
• Marine auxiliary engines: Control the rotational speed and power of Marine auxiliary engines.
• Industrial engines: Off-road engines for driving compressors, water pumps, mining machinery, and construction machinery.
• Oil and gas field equipment: Driving drilling, fracturing and power generation equipment in environments with high explosion-proof requirements.
Model Analysis: 5466-409
• 5466: This is the specific model code given by Woodward to its UG-40 series governors. Ug-8, UG-10, UG-25 and UG-40 are the common sizes of the UG series. The numbers roughly represent the output torque or power capacity. 5466-409 usually corresponds to the size specification of UG-40 and is suitable for medium to large engines.
• -409: This is a factory configuration code, usually indicating specific options for the governor, such as:
◦ Adjustable spring range (e.g., corresponding to 800-1500 rpm or other speed ranges).
◦ The type and size of the installation flange.
Does it include any additional functions (such as shut-off valves, types of speed regulation mechanisms, etc.)?
