Series D*1FE pilot operated proportional valves are designed for high precision applications that require a safe middle position of the main spool at power down.

The pilot is a 3-position valve with an overlapped middle position. This ensures that the main stage spring pushes the spool into the middle position at power down without an unintended jerk of the actuator.

The D*1FE series is available in 5 sizes:

  • D31FE NG10 (CETOP 5)
  • D41FE NG16 (CETOP 7)
  • D91FE NG25 (CETOP 8) for port diam. up to 32 mm
  • D111FE NG32 (CETOP10)

The innovative integrated regenerative function in the A-line (optional) allows new energy saving circuits with differential cylinders. The hybrid version can switch between regenerative mode and standard mode at any time.
