Small actuating cylinders need resolution rather than flow. This size 10 servo valve works with 10 l/min nominal flow, 19 l/min at most, at 350 bar operating pressure. External pilot oil supply separates the pilot stage from main pressure, and the valve weighs 3.87 kg.

The smaller the cylinder, the more the fine resolution of the valve decides control quality. At 10 l/min nominal flow the 4WS2EM10-5X/10B11XHT315K31EV is the finest step of this range and still holds 350 bar operating pressure.
Benefits
- 10 l/min nominal flow for fine positioning steps, with a 19 l/min peak.
- 350 bar operating pressure in size 10 to the ISO 4401-05-05-0-05 interface.
- External pilot oil supply, internal pilot oil return, useful where a dedicated pilot circuit exists.
- CCC-Ex with Ex TR type examination certificate for axes in classified areas.
- 3.87 kg weight, FKM seals, HL hydraulic fluid, 30 mA command value through external electronics.

Application
The valve serves servo axes with small swept volume, for example in material testing machines, simulators and control flaps. Low nominal flow keeps loop gain moderate and makes stable tuning easier. Where more speed is required, the same range offers 20, 30 and 45 l/min steps.
