Characteristics
NEW: A-regeneration D*1FER
The new series of pilot operated proportional valves
D*1FE is 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 (CETOP05)
D41FE NG16 (CETOP07)
D81FE NG25 (CETOP08) for port diam. up to 26 mm
D91FE NG25 (CETOP08) 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 be-
tween regenerative mode and standard mode at any time.
Technical features
• High dynamics
• High flow
• Defined spool positioning at power-down
• Onboard electronics
• NEW: Energy saving A-regeneration optionally
integrated
• NEW: Switchable hybrid version
Further literature about the opportunities of energy
savings and more functional details of the integrated
regeneration is available on request.
