Proportional Directional Valve 4WRTE25W6-350L-4X/6EG24K31/F1M - Bosch Rexroth R901079443

Without feedback the spool position drifts with temperature, friction and flow forces. The 4WRTE25W6-350L-4X measures spool position internally and corrects it continuously, at 350 l/min nominal flow and up to 870 l/min total flow.

Benefits

• Internal spool position feedback for high repeat accuracy
• 350 l/min nominal flow, 870 l/min maximum flow
• Spool symbol W6, three switching positions, four ports
• External pilot oil supply and external pilot oil return
• Analog 4 to 20 mA command value, on-board electronics, 350 bar operating pressure

Applications

Required in force and position control loops that must stay equally accurate over the full stroke, for example on materials testing machines and calibration presses. The external pilot circuit provides constant pilot pressure for this. Through ISO 4401-08-08-0-05 the valve is interchangeable with other size 25 types.
