Small cylinders under fine force control need a low nominal stage, otherwise the loop turns restless. The 4WS2EM10-5X/10B11XHET210K31EV-100 works with 10 l/min nominal flow, passing up to 19 l/min. It is rated to 2014/34/EU, equipment group II 1G.

Total price
An oversized servo valve makes a small axis twitchy, because a slight signal change already moves a lot of oil. The 4WS2EM10-5X/10B11XHET210K31EV-100 therefore meters only 10 l/min nominal flow, at operating pressures up to 350 bar.
Benefits
- 10 l/min nominal flow gives very fine resolution, with maximum flow held to 19 l/min.
- Explosion protection to 2014/34/EU, equipment group II 1G, plus CCC-Ex conformity.
- Direct actuation with internal pilot oil supply as well as internal return, 4 switching positions.
- Analog command value 30 mA/85 from external electronics, 24 VDC supply, 2 ports.
- 3.84 kg weight on subplate mounting to ISO 4401-05-05-0-05, FKM seals.

Application
The small nominal stage suits test cylinders, clamping axes plus positioning drives with low swallowing volume. Limited flow keeps loop gain low, which makes the axis easier to tune. In hazardous areas the electronics stay outside the zone.
Manufacturer
Bosch Rexroth, material number R901360749, product family 4WS2EM 10 XH -100. The explosion protected version requires a matching certified amplifier.
