Proportional Directional Valve 4WRKE25W8-350P-3X/6EG24ETK31/F1D3M - Bosch Rexroth R901538393

When 350 l/min nominal flow is required but the power unit provides no second control circuit, the valve has to supply itself. This size 25 version has internal pilot oil supply and internal pilot oil return, a linear characteristic curve with fine control range, and evaluates the 4...20 mA current command value at the unit itself.

Benefits

• Internal pilot oil supply and internal pilot oil return, no additional lines
• 350 l/min nominal flow, maximum 870 l/min across the valve
• Linear characteristic curve with a fine control range, spool symbol W8
• 4...20 mA command value, 24 VDC supply voltage, on-board electronics
• NBR seals, operating pressure up to 350 bar, weight 17.8 kg
