Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R900724553

This size 10 valve controls an actuator at 50 l/min nominal flow. Pilot oil is taken internally but returned externally, which decouples the pilot stage from the counter pressure of a shared return line.

Benefits

• External pilot oil return protects the pilot stage against counter pressure in a shared return line
• Internal pilot oil supply without an additional pressure line
• 50 l/min nominal flow, 170 l/min maximum flow, 315 bar operating pressure
• Spool symbol W6, 3 switching positions across 4 ports
• On-board electronics with ±10 V command, 7-pole connector (6 + PE) to EN 175201-804

Applications

The typical location is a manifold carrying several axes that work in parallel. Return pressure there changes with the number of active actuators. At 8.48 kg and with FKM seals the valve is released for HL hydraulic fluid.
