Proportional Directional Valve 4WRLD16W6-200LJ-4X/MPT/24ED6T - Bosch Rexroth R901523959

A manifold without pilot ports is enough for the 4WRLD16W6-200LJ-4X/MPT/24ED6T, because pilot oil supply along with the drain run internally. In exchange, operating pressure is capped at 280 bar. The spool of symbol W6 meters 250 l/min nominal flow, 800 l/min at peak.

Benefits

• Internal pilot oil supply with internal pilot oil return, no extra drillings in the manifold.
• Operating pressure up to 280 bar, the ceiling of this internally supplied version.
• 250 l/min nominal flow, flow up to 800 l/min, spool symbol W6.
• Digital axis controller on the valve, +/-10 V command value, 24 VDC supply.
• 12-pole connector (11 + PE) to EN 175201-804, 3 switching positions on 4 ports.
• NBR seals, hydraulic fluid HL, mass 12.66 kg, UKCA to EMC SI2016/1091.

Applications

The variant suits compact power units plus retrofits that lack a pilot pressure circuit while system pressure stays below 280 bar anyway. Mounting pattern ISO 4401-07-07-0-05 matches size 16. Higher pressures call for a version with external pilot supply.
