Proportional Directional Valve 4WRZE32W6-520-7X/6EG24EK31/A1D3V - Bosch Rexroth R901251106

This version combines spool symbol W6 with the classic ±10 V voltage command that analog cards and many PLC outputs supply directly. The signal path stays short and the on-board electronics remove the need for a separate amplifier. Hydraulically there are 520 l/min nominal flow and 350 bar operating pressure, and the valve weighs 44 kg.

Key benefits

• Spool symbol W6 with ±10 V command value straight from the analog card
• 520 l/min nominal flow in size 32, flow ceiling 1600 l/min
• 350 bar maximum operating pressure, connection diagram ISO 4401-10-09-0-05
• FKM seals for HL hydraulic fluid
• On-board electronics, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804
• 44 kg weight, 12.6 kg lighter than the otherwise comparable current-interface build

Technical data

Applications

Fits presses, test rigs and forming plants whose control system already outputs voltage command values and whose axis layout calls for symbol W6. Internal pilot oil supply with external pilot oil return keeps the piping simple. The FKM seal set is rated for permanently warm HL mineral oil.
