Servo Directional Valve 4WS2EM10-5X/20B11XLT210K31EV-102 - Bosch Rexroth R901518802

Servo axes in plants with IECEx requirements need a valve whose conformity is documented. This directly actuated size 10 servo valve is driven by a 30 mA current command value from external electronics and delivers 20 l/min nominal flow at operating pressures up to 315 bar.

Benefits

• 30 mA current command value from external electronics, less sensitive on long cable runs than a voltage signal.
• 20 l/min nominal flow and up to 40 l/min maximum flow at 315 bar operating pressure.
• IECEx conformity evidenced by a technical report.
• FKM seals widen the temperature and fluid range compared with NBR.
• External pilot oil supply with internal return - pilot pressure stays independent and no separate return line has to be run. ISO 4401-05-05-0-05 mounting pattern, 4 kg.

Application

Typical duties are force and position control on test benches and servo axes in process plants where IECEx documentation is required. The external electronics provide the controller and the output stage, the valve provides the manipulated variable. At 4 kg and with the size 10 mounting pattern it fits common subplates.
