Proportional Directional Valve 4WRZE10E1-85-7X/6EG24K31/A1M - Bosch Rexroth R901178507

Accumulator circuits and plants with pressure reduction need their own supply for the pilot stage. The 4WRZE10E1-85-7X/6EG24K31/A1M routes pilot oil supply and return externally and works at 85 l/min nominal flow in size 10.

Benefits

• External pilot oil supply and return through X and Y lines, independent of main pressure.
• 85 l/min nominal flow, up to 170 l/min maximum.
• Spool symbol E1 with internal spool position feedback.
• Command value ±10 V, on-board electronics at 24 V DC.
• 8.66 kg weight at 315 bar maximum operating pressure, UKCA to SI2016/1091.

Applications

This version is needed when system pressure is reduced during the sequence or an accumulator discharges and the axis still has to stay controllable. The Y line must run to tank without pressure. Connection diagram ISO 4401-05-05-0-05, seals in NBR.
