Proportional Directional Valve 4WRLE27V600L-4X/VXY/24F1 - Bosch Rexroth R901454558

Systems with their own pilot pump or with back pressure in the tank line need a valve whose pilot stage does not depend on the main circuit. The 4WRLE27V600L-4X/VXY/24F1 is fed and drained externally while handling 600 l/min nominal flow at 270 bar.

Benefits

• External pilot oil supply and external pilot oil return, keeping pilot pressure independent of the main circuit.
• 600 l/min nominal flow, 1850 l/min peak in size 27 to the ISO 4401-08-07-0-05 interface.
• 270 bar operating pressure with symbol V, three switching positions and four ports.
• Internal spool position feedback for high repeat accuracy, command value 4 to 20 mA at 24 VDC.
• 20.7 kg valve weight, FKM seals and HL hydraulic fluid, CE conformity.

Application

Typical hosts are power units where a separate pilot circuit provides constant control pressure. On plants with back pressure in the tank line the pilot stage still drains cleanly. A flow of 600 l/min serves large cylinders in forming and testing equipment.
