Optimised for smooth performance

Char-Lynn spool valve motors distribute pressurised fluid into and out of the orbit gear set via valve slots integrated into the output shaft. You can optimise the valve for low-flow, low-speed needs to ensure smooth operation.

Designs based on the orbit principle

Our premium line of Char-Lynn motors features a design based on the orbit principle, in which an internal gear rotates inside of an external fixed gear. These gerotor motors are known for their reliable high-power density, modularity and economic design.
