Total price
A mould oscillation repeats the same motion millions of times, and deviations show up at once in the strand surface. The 4WRKE25E220L-3X/6EG24K31/F1D3V keeps it stable at 220 l/min rated flow, 350 bar maximum and internal piston position feedback.
Benefits
- 220 l/min rated flow, matched to axes with a high cycle count rather than maximum throughput.
- Internal piston position feedback and a linear characteristic for repeatable amplitudes.
- Flow up to 870 l/min, operating limit 350 bar, size 25.
- External pilot oil supply and external pilot oil return, pilot operated spool.
- Current command value 4...20 mA, 24 VDC, 17.93 kg, FKM seals, ISO 4401-08-08-0-05.
