Total price
An axis whose system pressure drops sharply during the cycle drives its main valve more reliably from a separate control oil source. The 4WRKE16E1-220L-3X/6EG24K31/F1D3V works with external pilot oil supply and external return and carries 220 l/min nominal flow.
Advantages
- External pilot oil supply and external pilot oil return
- 220 l/min nominal flow, maximum flow 460 l/min
- Linear characteristic curve, spool symbol E1, three switching positions
- Command value 4...20 mA, on-board electronics with internal spool position feedback
- Maximum operating pressure 350 bar, interface ISO 4401-07-07-0-05
- FKM seals for HL, 24 VDC, 11 kg

Applications
The valve suits plants with a separate control oil pump, for example large presses and test rigs. Routing the pilot oil externally keeps switching times stable even at low main pressure. The current command value stays unambiguous over long cable runs.
