Proportional Directional Valve 4WRKE10E25L-3X/6EG24EK31/A1D3V - Bosch Rexroth R901157400

Short infeed steps only work out if the valve converts small command increments cleanly. At 25 l/min nominal flow the 4WRKE10E25L-3X/6EG24EK31/A1D3V works with a small rating in size 10 and therefore resolves the range around the centre position finely, at up to 315 bar operating pressure.

Benefits

• 25 l/min nominal flow, fine resolution for short and slow movements
• 150 l/min maximum flow as the upper limit, leaving headroom for rapid traverse
• 315 bar operating pressure at only 8.38 kg on the ISO 4401-05-05-0-05 pattern
• Internal position feedback with on-board electronics, the ±10 V command value is processed directly
• Internal pilot supply and external pilot drain, independent of tank line pressure

Applications

Typical duties are infeed axes on grinding and honing machines, clamping cylinders and adjusting movements on rolling stands. Where an axis travels only a few millimetres per cycle, valve resolution decides repeat accuracy. The FKM seals are matched to HL hydraulic fluid.
