Proportional Directional Valve 4WRZE10W9-85-7X/6EG24N9K31/F1D3V - Bosch Rexroth R900733703

The 4WRZE10W9-85-7X/6EG24N9K31/F1D3V is the current-input version of the series. A 4...20 mA command stays immune to voltage drop over long cable runs, and the on-board electronics evaluate it without an intermediate amplifier. Nominal flow is 85 l/min, 170 l/min at peak, at 315 bar. Both pilot supply and pilot return are routed externally through X and Y.

Benefits

• 4...20 mA current command instead of a voltage input, immune to line losses over long runs.
• Spool symbol W9, three switching positions, four ports, 85 l/min nominal flow.
• External pilot supply through X and external pilot return through Y, independent of the main circuit.
• Integrated pressure reducing valve stabilises the pilot level up to 315 bar operating pressure.
• FKM seals, 8.48 kg, mounting pattern ISO 4401-05-05-0-05.

Technical data
