Proportional Directional Valve 4WRZE10W8-85-7X/6EG24ETK31/F1D3M - Bosch Rexroth R901008981

The 4WRZE10W8-85-7X/6EG24ETK31/F1D3M brings the upper flow range of size 10 together with the simplest piping: 85 l/min nominal flow, pilot oil taken internally and returned internally. The 4...20 mA command value drives the spool of symbol W8, and operating pressure reaches 315 bar.

Benefits

• 85 l/min nominal flow, maximum flow 170 l/min at 315 bar operating pressure.
• Internal pilot supply and internal return remove the X and Y lines.
• Current command value 4...20 mA on on-board electronics, 24 VDC supply.
• Spool symbol W8, 3 switching positions, 4 ports, mounting pattern ISO 4401-05-05-0-05.
• Pressure reducing valve in the pilot stage secures pilot pressure under changing system pressure.
• Weight 8.47 kg, NBR seals, hydraulic fluid HL, UKCA conformity.

Application

The combination of high nominal flow and internal pilot routing suits infeed and feed axes in compact machines. Port P has to carry pressure throughout the cycle. Where the return line is heavily loaded, a version with external draining is the better choice.
