Proportional Directional Valve 4WRLE27E600LJ-4X/MPT/24A1 - Bosch Rexroth R901529149

Retrofits often stall because the existing manifold has no pilot channel. This NG27 version works with internal pilot oil supply plus internal pilot oil return, metering 600 l/min of nominal flow while allowing peaks to 1850 l/min at a maximum of 270 bar.

Benefits

• Internal pilot oil supply plus internal pilot oil return need no extra port
• Nominal flow of 600 l/min with spool symbol E, maximum flow 1850 l/min
• Operating pressure to 270 bar, connection diagram ISO 4401-08-08-0-05, CE conformity
• Linear characteristic curve with internal spool position feedback gives repeatable moves
• Command value ±10 V, 7-pole connector (6 + PE) to EN 175201-804, mass 20.8 kg

Application

A fit for replacements on existing large axes whose manifold carries no pilot channel. It presupposes a main circuit with enough pressure to drive the pilot stage. Typical cases are presses, forging plants plus hydraulic test fields.
