Proportional Directional Valve 4WRLE25W4-350SJ-4X/MPT/24A1-247 - Bosch Rexroth R901491104

Some axes have to creep in the fine range and still get the full cross section in rapid traverse. The 4WRLE25W4-350SJ-4X carries a progressive characteristic for that, translating small command values flatly and opening much wider at large ones.

Benefits

• Progressive characteristic gives fine resolution in the lower command range.
• Nominal flow of 350 l/min, maximum flow 1250 l/min.
• Internal pilot supply and internal return, X and Y lines fall away.
• Internal position feedback, spool symbol W4, three switching positions.
• Voltage command ±10 V on on-board electronics, supplied at 24 VDC.
• Mass of 19.1 kg, NBR seals, maximum operating pressure 350 bar, CE conformity.

Application

The progressive characteristic suits handling axes, positioning with a creep speed and test sequences spanning a wide speed range. For control loops with fixed gain a linear build makes more sense. Connection diagram ISO 4401-08-08-0-05 matches size 25.
