Proportional Directional Valve 4WRZE10W9-25-7X/6EG24N9K31/A1D3M - Bosch Rexroth R901241615

Small feed axes need a steady pilot pressure even when working pressure fluctuates. The 4WRZE10W9-25-7X/6EG24N9K31/A1D3M carries a pressure reducing valve for this and controls 25 l/min nominal flow from a ±10 V command value.

Benefits

• Built-in pressure reducing valve keeps pilot pressure steady while operating pressure moves up to 315 bar.
• Spool symbol W9 with three switching positions for fine metering around the centre position.
• 25 l/min nominal flow and flow up to 170 l/min across four ports.
• External pilot oil supply and external pilot oil return tie the valve into a dedicated pilot circuit.
• Concealed auxiliary actuation and ±10 V command value at the on-board electronics, 24 VDC supply.
• ISO 4401-05-05-0-05 connection diagram at 9.24 kg with NBR seals.

Technical data

Applications

The valve fits size 10 subplates and controls cylinders and motors on machine tools, handling equipment and test benches. A nominal flow of 25 l/min at 315 bar suits axes that have to be positioned accurately and approached slowly. UKCA conformity to SI2016/1091 covers the electromagnetic part of plant acceptance.
