Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9EK31/F1D3V - Bosch Rexroth R900949749

Jerky movement from a switching directional valve can be cured without reworking the manifold. The 4WRZE10W8-50-7X/6EG24N9EK31/F1D3V mounts on the same ISO 4401-05-05-0-05 pattern and meters 50 l/min steplessly at up to 315 bar.

Benefits

• Same interface as switching 4/3 directional valves in size 10 - exchange without a new manifold.
• 50 l/min nominal flow, 170 l/min maximum throughput, 315 bar operating pressure.
• 4...20 mA setpoint, so ramps stay reproducible even over long cable routes.
• Internal pilot supply, external return, mass 8.48 kg.
• Spool symbol W8, 3 switching positions, 4 ports, FKM seals.

Applications

Recommended for modernising older machines whose axes still start hard and shunt. On new installations the standardised interface saves design work too, since the manifold can stay unchanged.
