Proportional Directional Valve 4WRZE10W8-25-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901011741

At 25 l/min any disturbance in the pilot circuit weighs more heavily than it would on a large step. Pilot oil is therefore drained externally here and held constant by a pressure reducing valve, while the supply stays internal.

Benefits

• 25 l/min nominal flow, fine resolution through the ±10 V command value.
• Internal pilot oil supply with external drain, so tank pressure has no effect.
• Pressure reducing valve in the pilot circuit for constant switching times at 315 bar.
• Concealed manual override for commissioning and fault situations.
• 8.43 kg weight, spool symbol W8, NBR seals, ISO 4401-05-05-0-05 interface.

Applications

Fits positioning, clamping and infeed axes with a small cylinder. On manifolds with a shared return the external drain protects the null position. The 170 l/min maximum flow stays available as reserve.
