A 350 l/min nominal rating meets external pilot oil supply in the 4WRTE25W6-350L-4X/6EG24EK31/F1V. A large cylinder therefore travels briskly even when system pressure sags, under a 4...20 mA command at 350 bar.

Total price
Long strokes demand flow, and fluctuating system pressure must not slow the pilot stage down. The 4WRTE25W6-350L-4X/6EG24EK31/F1V combines both, with 350 l/min nominal flow at 350 bar operating pressure and an external pilot oil supply.
Benefits
- 350 l/min nominal flow, peaking at 870 l/min, for large size 25 cylinders.
- External pilot oil supply in the EK31 version makes the pilot stage independent of pressure in port P.
- A 4...20 mA current command for interference free transmission over long cables.
- Spool symbol W6, three switching positions, four ports, ISO 4401-08-08-0-05 mounting pattern.
- 350 bar operating pressure, FKM seals, 18 kg valve mass.

Application
Intended for presses and forging plants where large cylinders travel fast and pump pressure occasionally drops. The separate pilot oil line belongs in the planning. Size 25 calls for a subplate dimensioned to match.
