Where a dedicated pilot pump exists, external pilot supply is worth using. This servo valve takes pilot oil from outside, returns it internally and controls 45 l/min nominal flow at up to 90 l/min and 350 bar. Size 10, weight 3.84 kg.

Total price
A constant pilot pressure from its own source keeps servo axis dynamics stable even when main pressure drops during a cycle. The 4WS2EM10-5X/45B11XHT315K31EV uses an external pilot oil supply for exactly that and controls 45 l/min nominal flow at 350 bar.
Benefits
- External pilot oil supply, so control pressure stays constant while main pressure fluctuates.
- Internal pilot oil return, which saves one line at the subplate compared with the fully external version.
- 45 l/min nominal flow, 90 l/min maximum at 350 bar operating pressure.
- CCC-Ex conformity with Ex TR type examination certificate, size 10.
- 3.84 kg weight, FKM seals, analog 30 mA command value at 24 VDC.

Application
This version suits power units with a separate pilot pump, common in presses and large test installations. It keeps switching times reproducible even as system pressure falls. On plants without a pilot source of their own, the internally fed version is the simpler choice.
