Proportional Directional Valve 4WRZ10W9-50-7X/6EG24N9EK4/M - Bosch Rexroth R900619389

Where several valves relieve into a shared return line, counter pressure builds up. The 4WRZ10W9-50-7X/6EG24N9EK4/M therefore discharges its pilot oil separately and controls at 50 l/min nominal flow.

Benefits

• Internal pilot oil supply with external return, pilot stage clear of counter pressure in the common line.
• 50 l/min nominal flow, up to 170 l/min flow at 315 bar.
• Without a pressure reducing valve in the pilot stage, for plants with a regulated pilot pressure.
• Spool symbol W9, 3 switching positions across 4 ports to ISO 4401-05-05-0-05.
• 8.24 kg, 24 VDC, NBR seals, driven from external electronics.

Technical data

Applications

The application is in manifolds with several axes working onto a shared tank line. The separate pilot return keeps the step response independent of how many axes are moving at the time. The middle nominal step covers feed and brisk travel.
