Proportional Directional Valve 4WRZE25E220-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901110478

Pilot stage, reducing stage, electronics and main stage sit in one assembly here instead of four separate parts in the manifold. That shortens the parts list and the fault search, and the axis still gets 220 l/min with spool symbol E.

Benefits

• Four functions in one valve, which shortens both the parts list and the spares held on site.
• Pressure reducing valve in the pilot line, fed and drained through dedicated X and Y lines.
• Flow rating 220 l/min, maximum flow 870 l/min, operating pressure up to 350 bar.
• Current command 4...20 mA, on-board electronics, 24 VDC through a 7-pole connector (6 + PE).
• Spool symbol E, mounting face ISO 4401-08-08-0-05, mass 20.66 kg.

Applications

The design makes sense in plants whose maintenance has to get by with few part numbers, for example on press lines running shifts. Swapping the complete assembly brings the axis back in one step. Pilot oil arrives through X, the drain runs to tank through Y without pressure.
