When several large valves share one tank gallery, back pressure builds there and the pilot stage turns sluggish. The 4WRKE35E1000L-3X/6EG24K31/F1D3M avoids that, because pilot oil is fed in and led away externally. What it controls is a nominal flow of 1000 l/min at 350 bar, up to 3000 l/min maximum.
Benefits
- External pilot oil supply and external pilot oil return, keeping the pilot circuit independent of the main circuit.
- 1000 l/min nominal flow, up to 3000 l/min maximum, at 350 bar operating pressure.
- 60 kg weight in size 35, connection diagram ISO 4401-10-09-0-05.
- Spool symbol E with a linear characteristic curve and internal spool position feedback.
- On-board electronics with a 4...20 mA command value, 24 VDC supply through a 7-pole connector (6 + PE).
- NBR seals for hydraulic fluid HL with three switching positions across four ports.

Applications
The fully separated pilot circuit suits plants with many large valves working in parallel, such as press lines and water engineering. It calls for a dedicated pilot pressure supply that stays available even when the main circuit is unpressurised. That keeps the valve in a defined position as soon as the main pump shuts down.
