Total price
In hazardous areas many servo axes fail on missing approval papers rather than on dynamics. The 4WS2EM10-5X/20B11XHT315K31EV is listed with CCC-Ex and an Ex TR type examination certificate while controlling 20 l/min nominal flow at 350 bar.
Benefits
- CCC-Ex conformity with Ex TR type examination certificate, documented for use in classified zones.
- 20 l/min nominal flow, 40 l/min maximum in size 10 to the ISO 4401-05-05-0-05 interface.
- 350 bar operating pressure with direct actuation and three switching positions.
- External pilot oil supply with internal pilot oil return, so control pressure comes from a dedicated circuit.
- 3.7 kg weight with FKM seals for HL hydraulic fluid, 30 mA command value at external electronics.

Application
The valve controls force, position or speed on axes in chemical, oil and gas plants where an explosion protection approval is mandatory. At 20 l/min nominal flow it suits medium cylinders and servo test benches. Because the amplifier stays outside the valve, it can be mounted beyond the classified zone.
