We are committed to keeping your governors – whether new or old – running reliably and efficiently and for as long as you wish to keep them in service.

Can’t decide whether to Maintain or Upgrade your existing governors? Call your regional office today to speak with a seasoned governor specialist. They ‘know governors’ and can assist you with anything from a spare parts order to answering an application question to walking you through the completion of our Governor Decision Matrix. You may also peruse the other sections and subsections here on our website! If it’s related to a hydro governor, chances are good that we have what you’re looking for. Phone numbers and email addresses may be found on the Contact Us webpage. Like our motto says:

In addition to having a strong presence in the United States and Canada, American Governor Company is also a leading provider of governor parts, service, and upgrades throughout the world and is committed to expanding our international presence. We have already shipped governor parts or provided services to 60 countries worldwide.

For legacy governors ranging from mechanical flyball to analog electric to early digital governors, we offer new and refurbished parts, experienced field service and expert training. Mechanical governors have a much longer mean time between failure than digital products and with our huge inventory of new and reconditioned governor parts, we can often provide the part you need overnight to keep your units running reliably.

Our Factory Training and Repair facility provides complete factory repair and overhaul services for many types of governors, oil pumps and Permanent Magnet Generators. Our governor specialists can answer your maintenance questions and provide troubleshooting assistance right over the phone. We also offer factory and on-site training to customers who wish to build their staff’s familiarity with the maintenance and calibration of existing equipment.

Mechanical governors can pass any NERC or CIP tests for deadband and deadtime: no need to upgrade to digital control systems to comply with new regulations. With our expertise on legacy mechanical governors, digital conversion is no longer the only option. We can add functionality to existing mechanical units with 4-20 mA transmitters and limit switch assemblies for gate limit, gate position, and speed adjustment functions. Our abilities are unparalled.
