Proportional Directional Valve 4WRZE10W6-25-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900775563

Fine positioning axes turn 25 l/min into millimetre steps, so the resolution of the control spool decides the result. The 4WRZE10W6-25-7X/6EG24ETK31/A1D3M pairs that nominal flow with spool symbol W6, works up to 315 bar operating pressure and places both pilot oil paths internally.

Benefits

• Spool symbol W6 with 25 l/min nominal flow for fine positioning steps.
• Internal pilot oil supply and internal return, no separate pilot lines.
• Operating pressure up to 315 bar, maximum flow 170 l/min, size 10.
• Pressure reducing valve in the pilot circuit keeps the pilot pressure steady.
• Command value ±10 V, 24 VDC supply, weight 8.48 kg, NBR seals.

Technical data

Applications

Positioning axes on handling equipment, feed units and measuring set-ups work with such small flows. Because the electronics sit in the valve, the signal path back to the plant controller stays short and simple. The size 10 port pattern is identical to the higher-flow variants.
