Proportional Directional Valve 4WRZE10W9-50-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901508655

This size 10 valve controls direction and speed at 50 l/min nominal flow. The NBR seals are matched to HL hydraulic fluid, while spool symbol W9 and the external pilot circuit define the switching behaviour.

Benefits

• NBR seals matched to HL hydraulic fluid, the standard answer for mineral oil systems
• Spool symbol W9 with 3 switching positions across 4 ports
• 50 l/min nominal flow, maximum flow 170 l/min, operating pressure up to 315 bar
• External pilot oil supply and return for manifolds with their own pilot pump
• 4...20 mA current command at the on-board electronics, 24 VDC supply

Applications

The usual location is a manifold in machine tools, hoists or test rigs filled with mineral oil. At 9.12 kg the valve should be firmly bolted to the subplate to ISO 4401-05-05-0-05. UKCA conformity to SI2016/1091 is documented.
