Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9ETK31/A1D3V - Bosch Rexroth R900921152

This size 10 proportional directional valve drives medium actuators at 50 l/min nominal flow. Neither pilot inlet nor pilot return needs its own line, so installation is limited to a standard subplate to ISO 4401-05-05-0-05.

Benefits

• Fully internal pilot stage: installation without any additional pilot lines
• 50 l/min nominal flow with headroom up to 170 l/min maximum flow
• Spool symbol W6, 3 switching positions, 4 ports, 315 bar operating pressure
• ±10 V command through the on-board electronics, no amplifier card required
• At 8.43 kg light enough to be mounted on moving assemblies

Applications

Applications range from feed axes on machine tools to clamping and chucking cylinders. The system pressure must exceed the pilot pressure demand and the tank line must be free of noticeable back pressure. UKCA conformity to SI2016/1091 documents the electromagnetic compatibility.
