Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9K31/F1D3V - Bosch Rexroth R900939922

The valve controls a size 10 actuator at 50 l/min nominal flow. Spool symbol W6 and the fully external pilot oil circuit make it the choice for circuits in which the pilot pressure comes from a dedicated source, commanded via 4...20 mA.

Benefits

• 50 l/min nominal flow for medium cylinders, with headroom up to 170 l/min maximum flow
• External pilot oil supply and return, independent of the pressure level in the main circuit
• Spool symbol W6 with 3 switching positions across 4 ports
• 4...20 mA current command and on-board electronics with 24 VDC supply
• Weight 8.53 kg, FKM seals, HL hydraulic fluid

Applications

The valve mounts on a subplate to ISO 4401-05-05-0-05, typically in machine tools and handling systems. Where several valves hang on one shared pilot circuit, external supply simplifies the design. The electrical connection uses a 7-pole connector (6 + PE) to EN 175201-804.
