  • Small but powerful, Eaton spool valve motors have the perfect combination of features for a variety of demanding applications, from harvesting equipment to food processing plants. With hydrodynamic journal bearings optimized for long life, these spool valve motors distribute pressurized fluid via integrated valve slots into the Gerotor or Geroler® orbit gear set. This results in a spool valve section that can be optimized for low-flow low-speed requirements, keeping equipment performing smoothly.


  • Integrated proven orbit motor principle results in a compact yet powerful package
  • Hydrodynamic journal bearings extend bearing life
  • Three-zone pressure design allows for an increased shaft seal and bearing life
