Proportional Directional Valve 4WRKE10W6-50L-3X/6EG24ETK31/A1D3V - Bosch Rexroth R901231788

A feed drive in the low speed range needs fine resolution around the null position. The pilot-operated proportional directional valve 4WRKE10W6-50L-3X/6EG24ETK31/A1D3V works with the smaller 50 l/min rating in size 10 and holds up to 315 bar operating pressure without any external pilot line being routed.

Benefits

• 50 l/min nominal flow, the smaller rating of size 10 for sensitive feed movements
• Pilot oil supplied and drained internally, no separate pilot line on the manifold
• Spool symbol W6 with a linear characteristic curve, flow follows the command value proportionally
• Command value ±10 V on the on-board electronics, a 24 VDC supply is sufficient
• 315 bar operating pressure, 8.4 kg, FKM seals for HL hydraulic fluid

Applications

The valve suits feed axes on machine tools, infeed movements and small positioning axes where resolution matters more than volume. The ISO 4401-05-05-0-05 interface is the same as on the larger ratings of the series. Changing the flow rating therefore needs no rework of the manifold.
