Proportional Directional Valve 4WRZE25W8-325-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R900949807

A size 25 axis can be built without extra pilot oil piping when the pilot stage is fed and drained internally. This version meters 325 l/min nominal flow and works at up to 350 bar operating pressure.

Benefits

• Internal pilot oil supply and internal pilot oil return remove the need for separate pilot lines.
• 325 l/min nominal flow, maximum flow 870 l/min, maximum operating pressure 350 bar.
• Spool symbol W8, 3 switching positions, 4 ports, connection diagram ISO 4401-08-08-0-05.
• Command value 4 to 20 mA, 24 VDC supply, 7-pole connector (6 + PE) to EN 175201-804.
• Weight 20.78 kg, FKM seals, HL hydraulic fluid, pressure reducing valve in the pilot stage.

Technical data

Applications

Suited to presses, lifting gear and test benches whose main circuit carries pressure continuously and therefore feeds the pilot stage. A 4 to 20 mA current command stays stable over long cable runs. If system pressure disappears during holding, an externally piloted version is required.
