Proportional Directional Valve 4WRZE10W8-25-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901088012

Even a small axis can sit on a manifold with its own pilot supply. This version uses it through external supply and external drain and turns the 4...20 mA current command value into 25 l/min nominal flow.

Benefits

• 25 l/min nominal flow at 315 bar, maximum flow 170 l/min.
• External pilot oil supply and external pilot oil drain for a self-contained pilot circuit.
• 4...20 mA command value, insensitive to voltage drop on long cables.
• Pressure reducing valve in the pilot circuit, concealed manual override.
• 8.46 kg weight, spool symbol W8, NBR seals, ISO 4401-05-05-0-05 interface.

Technical data

Applications

Found on multi-axis manifolds where a small axis works next to large consumers. The dedicated pilot circuit keeps switching times constant when the neighbouring axis draws pressure. 25 l/min is enough for clamping and infeed movements.
