Proportional Directional Valve 4WRKE25E350L-3X/6EG24K31/F1D3V - Bosch Rexroth R901114885

When the control signal travels a long cable to the valve, a 4...20 mA current command value is the more interference-proof choice. This pilot-operated size 25 proportional valve accepts exactly that signal, passes 350 l/min nominal flow and is fed by a separate pilot circuit through external pilot oil supply and external pilot oil return.

Benefits

• Analog control with a 4...20 mA command value, insensitive to voltage drop on the signal line
• 350 l/min nominal flow with a maximum of 870 l/min across the valve
• External pilot oil supply and external pilot oil return keep pilot pressure decoupled from working pressure
• Spool symbol E, linear characteristic curve, internal spool position feedback
• Operating pressure up to 350 bar, FKM seals, weight 17.84 kg

Applications

Typical use is in power units with a central pilot supply, for example in rolling mills and large presses. At 350 l/min nominal flow the valve also moves cylinders of large bore quickly. The manifold follows the ISO 4401-08-08-0-05 port pattern.
