Proportional Directional Valve 4WRZ10E85-7X/6EG24K4/M - Bosch Rexroth R900711153

A control circuit fed independently of load pressure keeps its control quality even under strong pressure swings. The 4WRZ10E85-7X/6EG24K4/M is built with external pilot oil supply and external return for that, at 85 l/min nominal flow and 315 bar operating pressure.

Benefits

• External pilot routing in both directions, pilot oil and return run separately from the main circuit.
• 85 l/min nominal flow at 170 l/min maximum flow.
• Spool symbol E across three switching positions for controlled cylinder and motor axes.
• 315 bar maximum operating pressure, subplate mounting to ISO 4401-05-05-0-05.
• 7.74 kg weight, controlled with 24 V DC through external electronics.

Application

The valve is used in presses, test rigs and hydraulic axes with changing loads. A pressure reducing valve in the pilot stage is not included, so the pilot supply has to be sized accordingly.
