Proportional Directional Valve 4WRLE27E600LJ-4X/MPY/24A1 - Bosch Rexroth R901449275

Needing 600 l/min does not automatically mean reaching for size 32. This NG27 version provides the same nominal flow at a mass of only 20.15 kg, allows peaks to 1850 l/min plus works at a maximum operating pressure of 270 bar.

Benefits

• Nominal flow of 600 l/min at only 20.15 kg, clearly lighter than an NG32 solution
• Maximum flow of 1850 l/min gives reserve for rapid traverse phases
• Spool symbol E with linear characteristic curve plus internal spool position feedback
• Internal pilot oil supply with external pilot oil return, ±10 V command value on 24 VDC
• Operating pressure to 270 bar, connection diagram ISO 4401-08-07-0-05, CE conformity

Application

Meant for large axes on presses plus test rigs running 270 bar system pressure. Against an NG32 valve, both mass along with manifold area drop noticeably. Closed-loop spool control runs entirely in the on-board electronics of the valve.
