Proportional Directional Valve 4WRZ10W9-85-7X/6EG24N9ETK4/V - Bosch Rexroth R900970192

Where a medium axis has to accelerate and position steplessly, size 10 is sufficient and saves space compared with the next frame size. The pilot-operated proportional directional valve 4WRZ10W9-85-7X/6EG24N9ETK4/V delivers a nominal flow of 85 l/min there and handles up to 170 l/min at 315 bar.

Benefits

• Nominal flow 85 l/min, maximum flow 170 l/min in size 10.
• Operating pressure up to 315 bar, FKM seals for HL hydraulic fluid.
• Spool symbol W9, three switching positions on four ports, without pressure reducing valve.
• Internal pilot oil supply and internal pilot oil return, concealed auxiliary actuation.
• Electrical control with external electronics, 24 VDC, connector 7-pole (6 + PE) to EN 175201-804, weight 7.76 kg.

Application

The valve controls feed drives, swivel actuators and test rig axes with continuous speed setpoints. Control is handled by external amplifier electronics that convert the command value into solenoid current. It is mounted on a subplate to ISO 4401-05-05-0-05.
