Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9EK31/F1D3V - Bosch Rexroth R901460015

Return line back pressure distorts the characteristic of an internally drained pilot stage. This size 32 valve avoids that by combining internal pilot oil supply with an external pilot oil return, so the pilot stage drains through its own line straight to tank. Nominal flow is 520 l/min, operating pressure reaches 350 bar and the command value is 4 to 20 mA.

Key benefits

• External pilot oil return with internal supply keeps pilot pressure independent of tank line pressure
• 520 l/min nominal flow, up to 1600 l/min maximum
• 350 bar operating pressure, subplate mounting to ISO 4401-10-09-0-05
• 4 to 20 mA current command into the on-board electronics, 24 VDC supply
• Spool symbol W6, 3 switching positions, 4 ports, concealed auxiliary actuation
• 43.38 kg weight, FKM seals, HL hydraulic fluid

Applications

The configuration fits systems with a long return run, a return filter or an oil cooler, where measurable pressure sits at the tank port. Presses and test benches with high flow cylinders are the usual hosts. Working lines still land on the standard subplate and only the pilot drain needs its own connection.
