Proportional Directional Valve 4WRLE27W6-430LJ-4X/MXY/D24A1 - Bosch Rexroth R901467128

Size 27 covers the range where size 25 is already running out of room. The 4WRLE27W6-430LJ-4X provides 430 l/min nominal flow there, passes 1850 l/min at peak and positions the spool through internal feedback.

Benefits

• 430 l/min nominal flow in size 27, up to 1850 l/min maximum flow.
• Symbol W6, a defined overlap for axes that must stand safely in centre position.
• Operating pressure up to 270 bar, connection diagram ISO 4401-08-07-0-05.
• On-board electronics, command value ±10 V, no external amplifier needed.
• CE conformity documented, external pilot oil supply plus external pilot oil return.
• 20.92 kg, NBR seals, HL hydraulic fluid.

Applications

The valve drives main axes on presses and power units with high volume demand. A flow reserve of 1850 l/min allows short rapid traverse times without pushing the valve into saturation. Four ports plus three switching positions keep the installation conventional.
