Proportional Directional Valve 4WRZE10E1-85-7X/6EG24N9EK31/F1M - Bosch Rexroth R901130247

Placing booms and long boom axes need an unpressurised pilot oil return because the line back to tank is long and builds up back pressure. The 4WRZE10E1-85-7X/6EG24N9EK31/F1M therefore routes the pilot oil return outside, taps pilot oil internally and regulates 85 l/min nominal flow through spool symbol E1.

Benefits

• Internal pilot oil supply with external pilot oil return for a pilot stage free of back pressure.
• Spool symbol E1, 85 l/min nominal flow, maximum flow 170 l/min.
• Operating pressure up to 315 bar across four ports to ISO 4401-05-05-0-05.
• Version without pressure reducing valve, with concealed auxiliary actuation.
• Command value 4...20 mA, 24 VDC supply, weight 8.66 kg.

Applications

Concrete pumps, placing booms, truck mounted pumps and long boom axes take the pilot oil return separately to tank. The current interface bridges longer cable lengths without a loss of level. The size 10 subplate mounting stays the same as on other variants of the series.
