Direct Drive Valves, Proportional Valves and Servovalves

History

Since march 2017, FACT SAS innovates as a start-up, on proportional valves products called either Direct Drive Valves (DDV), or servovalves (servo-valves), or limited angle torque motors.

Direct Drive Valves modeling view

Direct Drive Valves Products

These valves are used for actuator’s precision positioning or fluid metering (hot air, fuel, hydrogen, oil).

Our in patent valves will provide benefits to our aerospace engine customers in term of component durability, cost and performances.

  • Up to 50% less parts
  • Contamination robustness thanks to relevant chip shear force
  • Direct drive valve actuation
