Proportional Directional Valve 4WRLE27W8-430LJ-4X/VXY/24A1 - Bosch Rexroth R901536846

A separate pilot circuit keeps control pressure steady even when working pressure collapses. The 4WRLE27W8-430LJ-4X/VXY/24A1 therefore takes pilot oil externally with an external return, at 430 l/min of nominal flow.

Benefits

• External pilot oil supply with external return, independent of the working pressure at the axis.
• 430 l/min nominal flow, peak figure 1850 l/min in size 27.
• Spool symbol W8 with FKM seals for warm oil.
• Command value ±10 V, supply 24 V DC through a 7-pole connector.
• 20.46 kg on connection diagram ISO 4401-08-08-0-05, operating pressure to 270 bar.

Applications

Planned for plants where several valves share one common pilot circuit. Control pressure then stays stable through load changes. Three switching positions, four ports, HL hydraulic fluid, CE.
