Proportional Directional Valve 4WRZE10W8-85-7X/6EG24ETK31/A1D3V - Bosch Rexroth R901072669

Whether an axis stops dead or is free to coast when switched off is set by the spool symbol. The 4WRZE10W8-85-7X works with symbol W8 and meters 85 l/min nominal flow at 315 bar in its end positions.

Benefits

• Symbol W8 - a defined mid position, matched to axes that hold by other means than the valve.
• 85 l/min nominal flow at 315 bar, up to 170 l/min maximum flow.
• Command value ±10 V, the sign sets the direction, 24 VDC supply.
• Pressure reducing valve in the pilot circuit and internal pilot routing without X or Y galleries.
• 8.48 kg, FKM seals, UKCA to SI2016/1091, size 10.

Application

Intended for axes that should not be clamped when de-energised, feeds with an external brake for instance. The ±10 V voltage command suits most axis controllers without a signal converter. Loads that have to be held still need a load holding valve of their own.
