Servo Directional Valve 4WS2EM10-5X/45B11XHE315K31EV - Bosch Rexroth R901177313

Back pressure in the tank line shifts the pilot zero point and costs control quality. The 4WS2EM10-5X/45B11XHE315K31EV therefore takes the pilot oil return outside while working at 45 l/min nominal flow and 350 bar.

Benefits

• Internal pilot oil supply, external pilot oil return, keeping the pilot stage clear of tank back pressure.
• 45 l/min nominal flow with a 90 l/min peak in size 10.
• 350 bar operating pressure to the ISO 4401-05-05-0-05 interface for subplate mounting.
• CCC-Ex with Ex TR type examination certificate for plants with zone requirements.
• 3.86 kg weight, analog 30 mA command value through external electronics at 24 VDC.

Application

The version pays off wherever several consumers share one return line and pressure remains in it. Typical hosts are test benches, clamping systems and servo axes in process plants. A nominal flow of 45 l/min covers medium cylinders running high cycle counts.
