For axes that must take a defined position at signal zero, spool geometry is the deciding factor. The 4WRZ10W6-85-7X/6EG24EK4/M combines symbol W6 with 85 l/min nominal flow, 170 l/min maximum flow and 315 bar operating pressure.
Benefits
- Spool symbol W6 across three switching positions for circuits with their own centre porting.
- 85 l/min nominal flow for fast travel of the axis.
- 315 bar maximum operating pressure through the ISO 4401-05-05-0-05 subplate mounting.
- Internal pilot oil supply with external return, which cuts external lines at the manifold.
- 8.24 kg weight, connected through a 7-pole connector (6 + PE) to EN 175201-804.
