Total price
A larger cylinder bore needs more oil, yet the manifold should stay as it is. The 4WRZE10W9-85-7X keeps size 10 and the ISO 4401-05-05-0-05 pattern while delivering 85 l/min nominal flow from a 4...20 mA command.
Benefits
- 85 l/min nominal flow without touching the manifold, range maximum flow 170 l/min.
- A 4...20 mA current command is insensitive to voltage drop along long cables.
- Internal pilot oil supply combined with external return keeps the pilot circuit relieved.
- Operating pressure to 315 bar, three switching positions, four ports, spool symbol W9.
- Weight 8.44 kg, 7-pole connector (6 + PE) to EN 175201-804, 24 VDC supply.
