Two details decide the choice inside the 4WRZ(E) series: the command signal and the routing of pilot oil. This variant works with plus/minus 10 V and feeds its pilot stage internally, with the pilot return staying inside the valve as well. At size 16 it meters 150 l/min and allows 460 l/min at the performance limit.
Benefits
- Command value plus/minus 10 V, direction included without extra enable logic.
- 150 l/min nominal flow at 350 bar operating pressure.
- Pilot oil in and out internally, no external pilot circuit needed.
- Spool symbol E3 with 3 switching positions and 4 ports.
- Concealed manual override for emergency operation and setup.
- 12.64 kg valve weight, mounts on any ISO 4401-07-07-0-05 subplate.
