Proportional Directional Valve 4WRLE10V1-100P-4X/MPY/24F1 - Bosch Rexroth R901499850

A few bar of back pressure in the return line is enough to shift the null position of a pilot-operated valve. This size 10 variant avoids that with its own pilot oil return to Y while metering 100 l/min nominal flow.

Benefits

• External pilot oil return through Y keeps the pilot stage clear of back pressure in the shared tank line.
• Internal pilot oil supply from port P saves the additional X pressure line.
• 4...20 mA command value for long cable runs, with live zero at 4 mA.
• Spool symbol V1 with fine control range, 100 l/min nominal, up to 300 l/min peak.
• Operating pressure up to 350 bar, CE conform, weight 9.1 kg.

Applications

This port arrangement fits power units where several valves work into one common return manifold, for instance units with return line filtration and cooling. Null position stays stable even over long return runs. The Y line has to be routed separately to tank.

Manufacturer

Bosch Rexroth lists the valve as R901499850, product family 4WRLE, NBR seals for HL hydraulic fluid.
