When the command cable runs across the whole shop floor, every voltage drop distorts a voltage signal. This size 25 proportional directional valve therefore takes a 4...20 mA current command and meters 350 l/min at 350 bar. Pilot oil is fed in externally and drained externally.

Driving a large cylinder from a control cabinet far away calls for a command signal that survives the cable run. The 4WRDE25V1-350L-6X/MXY/24F1 accepts a 4...20 mA current command and turns it through the V1 spool into 350 l/min nominal flow at 350 bar.
Benefits
- 4...20 mA current command through a 7-pole connector (6 + PE) to EN 175201-804, immune to voltage drop over long cable runs.
- 350 l/min nominal flow at 350 bar operating pressure, the size 25 body allows up to 870 l/min.
- On-board electronics on 24 V DC, so no amplifier card is wired into the cabinet.
- External pilot oil supply plus external pilot oil return keep the pilot circuit independent of main pressure.
- ISO 4401-08-08-0-05 interface with four ports, three switching positions and 17.5 kg installed weight.
