Proportional Directional Valve 4WRZ10E1-25-7X/6EG24N9EK4/D3M - Bosch Rexroth R901226730

When the shared return line carries counter pressure, a pilot stage works inaccurately. The 4WRZ10E1-25-7X/6EG24N9EK4/D3M therefore relieves its pilot stage into a separate line and controls at 25 l/min nominal flow.

Benefits

• Internal pilot oil supply, external return, the pilot stage stays clear of counter pressure.
• 25 l/min nominal flow, up to 170 l/min flow in size 10.
• 315 bar operating pressure, spool symbol E1 with 3 switching positions across 4 ports.
• Pressure reducing valve in the pilot stage, plus concealed auxiliary actuation.
• 8.2 kg, 24 VDC through a 7-pole plug (6 + PE) to EN 175201-804, NBR seals and HL fluid.

Applications

This version is wanted on machines with a return filter or a long tank line where pressure builds up. The fine 25 l/min step suits axes with a short stroke. An external amplifier card handles the drive and matches command value and valve current.
