Proportional Directional Valve 4WRZE10W9-85-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R901018548

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.

Applications

The version serves larger cylinders in presses, lift tables and clamping fixtures. Higher nominal flow shortens rapid traverse times while the existing sandwich stack stays untouched. NBR seals are fitted for mineral oils of class HL.
