Proportional Directional Valve 4WRLE27W8-430LJ-4X/VPY/24A1 - Bosch Rexroth R901546278

With permanently warm oil the seal material decides the service interval. The 4WRLE27W8-430LJ-4X/VPY/24A1 works with FKM, takes pilot oil internally, and meters 430 l/min of nominal flow at up to 270 bar operating pressure.

Benefits

• FKM seals for elevated oil temperatures in HL hydraulic fluid.
• Spool symbol W8 with a linear characteristic, 430 l/min nominal flow.
• Internal pilot oil supply, external return, only line Y is routed on the plant side.
• Command value ±10 V at the on-board electronics on 24 V DC.
• 20.46 kg, peak flow 1850 l/min, connection diagram ISO 4401-08-08-0-05.

Applications

Intended for plants running high oil temperatures, such as die casting machines or endurance test rigs. Because pilot oil comes from system pressure, a separate pilot pump is unnecessary. Four ports, three switching positions, CE conformity.
