Total price
The 4WRZE10E50-7X/6EG24N9K31/F1M separates the pilot stage entirely from the main circuit, with pilot oil supply and return both routed outside. Nominal flow is 50 l/min, operating pressure reaches 315 bar and the valve weighs 8.7 kg.
Advantages
- External pilot oil supply and external pilot oil return, independent of main pressure
- Nominal flow 50 l/min against a maximum flow of 170 l/min
- Operating pressure to 315 bar, E spool, 3 switching positions
- Concealed auxiliary actuation, built without a pressure reducing valve
- 4 to 20 mA command value, 24 V DC supply, 7-pole connector (6 + PE) to EN 175201-804
- UKCA conformity for electromagnetic compatibility SI2016/1091
