Proportional Directional Valve 4WRZ10E50-7X/6EG24K4/M - Bosch Rexroth R901104568

Where main circuit pressure swings widely, pilot oil should come from its own source. The 4WRZ10E50-7X/6EG24K4/M is built with external pilot oil supply and external return for that purpose, at 50 l/min nominal flow and 315 bar maximum operating pressure.

Benefits

• External pilot supply and return, keeping pilot pressure independent of load pressure.
• 50 l/min nominal flow, up to 170 l/min across four ports.
• Spool symbol E across three switching positions for controlled cylinder axes.
• 315 bar maximum operating pressure on the ISO 4401-05-05-0-05 interface.
• 7.76 kg weight, 7-pole connector (6 + PE) to EN 175201-804.

Application

The version is used in hydraulic axes with strongly varying load, for example in presses and test rigs. Pilot oil can come from an auxiliary unit or a filtered secondary circuit.
