General Description
Series D*1FP pilot operated servo proportional valves
transfer the advantages of the Parker patented Voice
Coil Drive (VCD
®
) to larger frame sizes for high flow
rates. The high dynamic / high precision drive of the
pilot valve allows the optimum control of the main spool
and results in servo performance of the complete valve.
Series D*1FP is available in 5 sizes:
D31FP NG10 (CETOP 5)
D41FP NG16 (CETOP 7)
D91FP NG25 (CETOP 8)
for port diameter up to 32 mm (1.26 in.)
D111FP NG32 (CETOP 10)
The power down mode works with a safe 4th position
of the D1FP pilot valve. This ensures that the main
stage is hydraulically balanced at power down and
allows the main spool spring to center (for overlapped
spools), or approximately 10% spring offset to spool
position A or B (for zerolap spools).
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.
