Servo Directional Valve 4WS2EM10-5X/30B11T315K31CV/3 - Bosch Rexroth R901571528
A control loop with high dynamics calls for a servo valve rather than a proportional valve. The 4WS2EM10-5X/30B11T315K31CV/3 runs 30 l/min nominal flow at 315 bar, is driven by a 30 mA signal and draws its pilot oil externally.

Description
In a closed force or position loop the corner frequency of the valve decides the quality. The 4WS2EM10-5X servo directional valve in version T315K31CV/3 takes 30 mA as command value, carries 30 l/min nominal flow and works on external pilot oil supply with internal pilot oil return.
Benefits
- 30 l/min nominal flow, up to 60 l/min, laid out for loops with fast setpoint changes.
- External pilot supply, internal return, pilot pressure stays steady even when system pressure fluctuates.
- 315 bar maximum operating pressure on the ISO 4401-05-05-0-05 pattern in size 10.
- Analog 30 mA command through external electronics, the valve ties into an existing loop controller.
- FKM seals at 3.91 kg weight, resistant to raised oil temperatures in continuous duty.
Applications
The valve is used in materials testing machines, in simulators and in control loops of forming technology, where force or travel is corrected continuously. External pilot supply pays off when main pressure dips in step with the machine cycle. The 7-pole connector to EN 175201-804 links the valve to the controller card.
Manufacturer
