Proportional Directional Valve 4WRLE16E250LJ-4X/MXY/24L1 - Bosch Rexroth R901524028

In plants with their own pilot pump, the decision for a digital fieldbus connection is often made as well. This 4WRLE16E250LJ combines both, driven over IO-Link on the 5-pole M12 connector while taking pilot oil externally at X and draining externally at Y. At 250 l/min nominal, internal position feedback controls the main spool and holds flow at the command value.

Benefits

• IO-Link on M12 x 1 with A coding, command value and diagnostics on one line.
• Fully separated pilot circuit through X and Y keeps stroke time constant.
• 250 l/min nominal flow, limit 800 l/min at 350 bar.
• Internal main spool position feedback, linear characteristic with symbol E.
• On-board electronics, 24 VDC supply, CE conformity.
• Valve weight 11.64 kg, port pattern ISO 4401-07-07-0-05.

Applications

The valve suits large presses and test rigs whose hydraulics have a dedicated pilot power unit and whose automation runs on IO-Link. On replacement the master restores the stored parameters, so no adjustment at the valve is needed. Without an IO-Link master the valve cannot be operated.
