Total price
Retrofitting a proportional axis costs time and space for every extra control line. The 4WRZE10W8-50-7X/6EG24N9ETK31/A1D3V needs none, because pilot oil supply and return both run internally, at 50 l/min and 315 bar.
Benefits
- Internal piloting in both directions - installation without additional control oil lines.
- ±10 V setpoint, matching most analogue cards already installed.
- 50 l/min nominal flow, 170 l/min maximum, 315 bar operating pressure.
- Mass 9.05 kg, ISO 4401-05-05-0-05 interface, 4 ports.
- On-board electronics, 24 VDC, 7-pole (6 + PE) connector to EN 175201-804.
