Proportional valves
General Description
Series D*1FB pilot operated proportional directional
valves come in 4 sizes:
D31FB NG10 (CETOP 5)
D41FB NG16 (CETOP 7)
D91FB NG25 (CETOP 8)
D111FB NG32 (CETOP 10)
The valves are available with and without onboard
electronics (OBE).
D*1FB OBE: The digital onboard electronics is situ-
ated in a robust metal housing, which allows usage
under rough environmental conditions.
The nominal values are factory set. The cable
connection to a serial RS-232 interface is available as
an accessory.
D*1FB for external electronics: The parameters can be
saved, changed and duplicated in combination with the
digital power amplifier PWD00A-400.
Series D*1FB valve parameters can be edited with the
common ProPxD software for both versions.
The D*1FB valves work with barometric feedback of
the main stage to the pressure reducing pilot valve.
The pilot control pressure of 25 Bar (363 PSI) allows
high flow rates of maximum of stability.
The innovative integrated regenerative function into
the A-line (optional) allows new energy saving circuits
for differential cylinders. The hybrid version can be
switched between regenerative mode and standard
mode at any time.
