Needing 600 l/min does not automatically mean reaching for size 32. This NG27 version provides the same nominal flow at a mass of only 20.15 kg, allows peaks to 1850 l/min plus works at a maximum operating pressure of 270 bar.
Benefits
- Nominal flow of 600 l/min at only 20.15 kg, clearly lighter than an NG32 solution
- Maximum flow of 1850 l/min gives reserve for rapid traverse phases
- Spool symbol E with linear characteristic curve plus internal spool position feedback
- Internal pilot oil supply with external pilot oil return, ±10 V command value on 24 VDC
- Operating pressure to 270 bar, connection diagram ISO 4401-08-07-0-05, CE conformity
