Proportional Directional Valve 4WRZE10W9-85-7X/6EG24N9ETK31/F1M - Bosch Rexroth R901443964

Anyone replacing a valve needs the spool symbol exactly right. Here it is W9, combined with 85 l/min nominal flow, internal pilot oil routing and a 4...20 mA command value at 315 bar operating pressure.

Benefits

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

Applications

Used on axes whose system pressure stays stable across the cycle and that need no pressure reducing valve of their own. The internal pilot path saves drillings in the manifold. 85 l/min covers larger cylinder areas.
