Servo Directional Valve 4WS2EM10-5X/10B11XHET210K31EV-100 - Bosch Rexroth R901360749

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.
