Proportional Directional Valve 4WRZE10E85-7X/6EG24N9K31/A1D3M - Bosch Rexroth R900763138

Running several valves from one central pilot supply calls for a version with external supply and external return. That is how the 4WRZE10E85-7X/6EG24N9K31/A1D3M is built, metering 85 l/min nominal flow with spool symbol E at operating pressures up to 315 bar.

Benefits

• Size 10 with spool symbol E, rated at 85 l/min nominal flow.
• Pilot oil comes from an external circuit and leaves through an external return, keeping pilot pressure separate from working pressure.
• The built-in pressure reducing valve holds pilot pressure steady while the main circuit runs up to 315 bar.
• Command value input ±10 V on the on-board electronics, wired through a 7-pole connector (6 + PE) to EN 175201-804 at 24 VDC.
• NBR seals, HL fluid, mounting pattern ISO 4401-05-05-0-05, maximum flow 170 l/min, 8.48 kg weight.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Applications

It is a common choice in power units that feed several axes from a shared pilot circuit. The 85 l/min cover fast approach movements without losing fine resolution in the lower command range. The concealed auxiliary actuation helps during commissioning.
