Proportional Directional Valve 4WRKE10W6-25L-3X/6EG24ETK31/F1D3M - Bosch Rexroth R901202900

The electronics sit on the valve in the 4WRKE10W6-25L-3X/6EG24ETK31/F1D3M, so no external amplifier is needed. The command value 4...20 mA arrives at the connector, the supply is 24 VDC, and 25 l/min nominal flow is controlled.

Benefits

• Pilot-operated spool valve rated 25 l/min, peaks to 150 l/min.
• On-board electronics handle the command value 4...20 mA without a separate amplifier.
• Spool with symbol W6, its position measured and corrected internally.
• Pilot oil supplied and returned internally, matched to the pilot oil routing of the system.
• Subplate mounting ISO 4401-05-05-0-05 in size 10, to 315 bar.
• 9.26 kg, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.

Applications

Typical locations are feed and infeed axes in machinery plus control loops inside hydraulic power units. Spool symbol W6 determines how the ports relate to each other in the centre position. The on-board electronics take the command value from the higher-level controller directly.
