Parts requiring replacement and the reason for it
Photographs of the regulator in its final state
Test curves (initial and final)
Manufacturer’s test sheet (initial and final)
Delivery note listing the P/N and S/N of the equipment

How can I get the technical sheet or user manual?

Feel free to visit the product sheet section to learn more about our speed regulation equipment.

3/ My equipment

How to find the serial number/part number?

These codes can be found on the nameplate on the regulator body.

What is the difference between the two?

The part number defines the type of equipment.
The serial number is the unique identifier of the equipment.

What are these numbers used for?

They precisely identify the type of equipment you own.
They also allow you to understand the specificities of your equipment.

What are the different types of regulators?

Hydro-Mechanical
Electronic

Can I adjust my regulator myself?

Adjusting a regulator requires a thorough understanding of its specific features.

Some adjustments can be made by the end user if they are familiar with the procedure and risks.

For warranty reasons, internal adjustments should only be made by those authorized by the manufacturers.

Why does a regulator become obsolete?

Equipment obsolescence is generally linked to the discontinuation of certain parts by the manufacturer. To learn more about Woodward equipment obsolescence, check our article on our modernization recommendations.

4/ Technical references

What type of oil should be used for hydraulic regulators?

For more details, a Woodward recommendation table on viscosity and temperature is available in the Guide Woodward Oils for Hydraulic Controls.

How often should the oil be changed?

This depends on the regulator’s function (main engine or generator) and temperature. Oil should be changed every 3,000 to 4,000 hours.

For more details, consult the Guide Woodward Oils for Hydraulic Controls.

What is checked during the inspection of a regulator in the workshop?

The degree of wear and the condition of each part.

What is the lifespan of a regulator?

NCG recommends performing equipment maintenance every 3 months or 15,000 hours of operation. This also depends on several factors:

The type of regulator
The maintenance performed
Its environment
The frequency of use

5/ Everything you need to know about speed regulation

What is speed regulation for?

Speed regulation controls the amount of driving energy allowed into a machine based on its environment (setpoint, load, pressure, etc.).

What is the difference between a regulator and an actuator?

A regulator controls the driving energy of a machine based on the setpoint applied. The actuator performs the action requested by a control signal but has no information about the setpoint. The actuator is usually associated with an electronic regulator.

What is a booster?

A booster is a starting aid device that compensates for the lack of oil pressure in the regulator at that precise moment.

Is it necessary to service the booster?

We recommend sending your booster for servicing at the same time as your regulator for a complete and optimal overhaul. Discover our article on the interest and importance of this revision.
