Proportional Directional Valve 4WRLF10W8-100LJ-4X/MPY00/24ND90 - Bosch Rexroth R901536746

Running two axes in step only works if flow follows the command value linearly. The 4WRLF10W8-100LJ uses symbol W8 for a linear characteristic and handles 100 l/min nominal flow at 280 bar, with up to 300 l/min at peak.

Benefits

• Linear characteristic, symbol W8, so command value and flow stay proportional across the whole stroke.
• Internal pilot oil supply with external return keeps the pilot circuit clear even when the tank line carries back pressure.
• 100 l/min nominal flow and up to 300 l/min peak on connection diagram ISO 4401-05-05-0-05.
• Integrated fieldbus electronics on 24 V DC with enable acknowledgment, 7-pole connector (6 + PE) to EN 175201-804.
• 280 bar operating pressure, NBR seals, three switching positions, weight 9.08 kg.

Applications

Typical work is synchronised motion on gantries, lifting tables and machine tool axes where two cylinders share one movement. The external pilot oil return pays off wherever the return line carries pressure. The valve is specified for HL hydraulic fluid.
