Large axes are often retrofitted into existing manifolds where there is no room left for additional pilot lines. The 4WRZE32W8-520-7X feeds its pilot stage internally and returns it internally, at 520 l/min nominal flow and up to 1600 l/min maximum flow.
Benefits
- Nominal flow 520 l/min, maximum flow 1600 l/min
- Internal pilot oil supply and internal pilot oil return
- Pressure reducing valve in the pilot stage keeps pilot pressure constant
- Spool symbol W8 with 3 switching positions across 4 ports
- Command value ±10 V, on-board electronics, connector 7-pole (6 + PE)
- UKCA declaration SI2016/1091, ISO 4401-10-09-0-05 interface
