Proportional Directional Valve 4WRLE16E250LJ-4X/MPT/24A1 - Bosch Rexroth R901440167

Many axes need neither a separate pilot pump nor a current loop. For that case the 4WRLE16E250LJ-4X/MPT/24A1 combines a plus or minus 10 V command with internal pilot oil supply and delivers 250 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• Plus or minus 10 V command at the on-board electronics, no additional signal converter needed.
• 250 l/min nominal flow at 350 bar against a series maximum of 800 l/min.
• Internal pilot oil supply and internal return through P and T.
• Spool symbol E, 3 switching positions, 4 ports, linear characteristic across the whole stroke.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals, weight 11.59 kg.

Technical data

Applications

Use ranges from feed axes on presses through lifting gear to positioning drives in special machinery. Because the spool is position controlled, the opening follows the command even against flow forces. Sealing is NBR for mineral oil of class HL.
