Servo axes with high dynamics need a directly actuated valve and external electronics to supply the command value. The 4WS2EM10-5X/90B11XHET210K31EV passes 90 l/min nominal flow at 350 bar and is driven by an analog 30 mA signal. FKM seals and the CCC-Ex certificate widen its field of use.

Total price
Control loops that have to respond within milliseconds call for a directly actuated servo valve rather than a pilot-operated stage. The 4WS2EM10-5X/90B11XHET210K31EV delivers 90 l/min nominal flow at 350 bar operating pressure in size 10.
Benefits
- Direct actuation without a pilot stage, nominal flow 90 l/min and up to 180 l/min maximum.
- 350 bar operating pressure in size 10 with mounting pattern ISO 4401-05-05-0-05.
- Analog control at 30 mA from external electronics on a 24 VDC supply.
- FKM seals, suitable for higher temperatures than NBR, with hydraulic fluid HL.
- CCC-Ex conformity with an Ex TR type examination certificate.
- Only 3.83 kg, light enough for use on moving assemblies.

Applications
The servo valve works in position and force control loops of test rigs, simulators and forming machines where short response times decide the result. Internal pilot oil supply and internal return save additional lines. The 7-pole connector to EN 175201-804 links the valve to the external control electronics.
Manufacturer
