Proportional Directional Valve 4WRZ10E1-85-7X/6EG24N9ETK4/D3V - Bosch Rexroth R900943060

On this valve the force for the main spool comes from the oil, not from the solenoid. The pilot stage of the 4WRZ10E1-85-7X/6EG24N9ETK4/D3V converts the electrical signal hydraulically, and 85 l/min nominal flow are controlled.

Benefits

• Pilot-operated design with pilot stage and main stage in one housing.
• 85 l/min nominal flow, up to 170 l/min at 315 bar maximum operating pressure.
• Internal pilot oil supply and internal pilot oil return, X and Y stay unpiped.
• Spool symbol E1, three switching positions, four ports, 24 V DC.
• Integrated pressure reducing valve and FKM seals, mass 8.22 kg.

Applications

The valve is used on controlled axes of medium power, for example in presses, test rigs and plastics machinery. The amplifier sits externally and is connected through a connector, 7-pole (6 + PE) according to EN 175201-804. The released hydraulic fluid is HL.
