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.

Technical data

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.
