When system pressure drops below the pilot demand during rapid traverse, the pilot stage needs its own circuit. This size 32 valve with spool symbol W6 works with external supply and external return at 360 l/min nominal flow.

During rapid traverse the system pressure collapses, yet the pilot stage needs a constant supply. The 4WRZE32W6-360-7X/6EG24N9K31/A1V draws it externally and returns the pilot oil externally, at 360 l/min nominal flow with spool symbol W6.
Benefits
- External pilot oil supply and external return, decoupled from main pressure
- Spool symbol W6 at 360 l/min nominal flow
- Maximum flow 1600 l/min, maximum operating pressure 350 bar
- Setpoint plus or minus 10 V, on-board electronics with spool position feedback
- Version without pressure reducing valve, concealed auxiliary actuation
- 43.8 kg weight, FKM seals for HL hydraulic fluid

Applications
Built for axes with pronounced rapid traverse phases, for instance in presses and forging plants. Because pilot supply and pilot return are routed separately, the valve stays controllable even at low system pressure.
