Large axes often sit far away from the control cabinet. This size 25 valve therefore accepts a 4...20 mA current command value and converts it into 350 l/min nominal flow at operating pressures up to 350 bar.
Advantages
- Command value 4...20 mA for interference-free transmission over long cables
- Nominal flow 350 l/min, maximum flow up to 870 l/min
- External pilot oil return with internal supply
- Symbol W6, three switching positions, four ports to ISO 4401-08-08-0-05
- Linear characteristic curve with fine control range, on-board electronics on 24 VDC
- Operating pressure up to 350 bar, 17.9 kg, NBR seals for HL hydraulic fluid
