A linear characteristic makes tuning the superimposed controller predictable. The 4WRKE25R3-350L-3X/6EG24K31/A1D3M works with spool symbol R3 and a linear curve, handling 350 l/min nominal flow at operating pressures up to 350 bar.
Benefits
- Linear characteristic with spool symbol R3, metering area follows the command value evenly.
- 350 l/min nominal flow, up to 870 l/min maximum flow, operating pressure up to 350 bar.
- External pilot oil supply and external return, the pilot stage runs on its own pressure.
- Internal spool position feedback, plus/minus 10 V command value, 24 VDC supply voltage.
- Three switching positions on four ports, ISO 4401-08-08-0-05 interface.
- 19.94 kg, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.
