Total price
High back pressure in the return line distorts pilot control. The 4WRZE32W6-520-7X/6EG24N9EK31/A1D3V therefore takes pilot oil internally from the main circuit but drains it externally and without pressure, controlling 520 l/min nominal flow from the ±10 V command.
Benefits
- Internal pilot oil supply with external pilot oil return, pilot stage kept clear of return line back pressure
- 520 l/min nominal flow, max. flow 1600 l/min
- Spool symbol W6, 3 switching positions, 4 ports
- ±10 V command, 24 V DC via 7-pole connector (6 + PE) to EN 175201-804
- Max. operating pressure 350 bar, FKM seals
- Weight 43.9 kg, interface ISO 4401-10-09-0-05
