Proportional Directional Valve 4WRZE10W9-50-7X/6EG24N9K31/A1D3M - Bosch Rexroth R901238292

With 50 l/min nominal flow this size 10 directional valve sits between the 25 l/min fine metering version and the fast 85 l/min version. The external pilot circuit makes the switching behaviour independent of the pressure profile in the main circuit.

Benefits

• 50 l/min nominal flow as the middle ground between fine resolution and fast stroke
• External pilot circuit keeps switching times independent of the pressure profile in the main circuit
• 315 bar operating pressure, maximum flow 170 l/min, 4 ports
• Spool symbol W9 with 3 switching positions and concealed auxiliary actuation
• ±10 V command, on-board electronics, NBR seals, weight 8.47 kg

Applications

Feed axes, lifting cylinders and clamping devices in machine tools are the usual cases. Where a pilot pump already exists, the system pressure no longer has to be considered. The valve is UKCA compliant to SI2016/1091.
