Proportional Directional Valve 4WRZE10W9-85-7X/6EG24N9K31/F1M - Bosch Rexroth R901327591

A pilot circuit fed from its own source and drained to tank without pressure needs no additional pressure reducing valve. This version with spool symbol W9 uses exactly that arrangement at 85 l/min nominal flow.

Benefits

• 85 l/min nominal flow, 170 l/min maximum flow at 315 bar.
• External pilot oil supply and external drain, without a pressure reducing valve in the pilot circuit.
• Spool symbol W9 with 3 switching positions, 4 ports to ISO 4401-05-05-0-05.
• 4...20 mA command value on on-board electronics, concealed manual override.
• 7.98 kg weight, NBR seals, 24 V DC supply, UKCA under SI2016/1091.

Applications

Fits plants with their own pilot power unit already delivering regulated pilot pressure. The external drain keeps the pilot stage clear of main circuit tank pressure. 85 l/min moves cylinders of larger area.
