Proportional Directional Valve 4WRZE10W8-85-7X/6EG24EK31/A1M - Bosch Rexroth R900974754

Pilot pressure is usually available in the main circuit, a clean return is not always. The 4WRZE10W8-85-7X/6EG24EK31/A1M therefore feeds internally and drains the pilot oil externally, at a nominal flow of 85 l/min.

Benefits

• Internal supply, external pilot drain, only the Y line is added.
• 85 l/min nominal flow with spool symbol W8, up to 170 l/min maximum.
• Command value ±10 V through on-board electronics at 24 V DC.
• 315 bar maximum operating pressure, connection diagram ISO 4401-05-05-0-05.
• 8.01 kg weight, NBR seals, UKCA to SI2016/1091.

Applications

The version makes sense on plants with a return filter, cooler or long tank line where back pressure builds up. The axis then stays cleanly controllable even under a heavily loaded return. Four ports and three switching positions serve a double acting cylinder.
