Proportional Directional Valve 4WRZE25W8-325-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R901052185

A current command of 4 to 20 mA rides through long cable runs without losing level, and that is what this valve follows. It meters 325 l/min nominal flow with spool symbol W8 and feeds its pilot stage internally, so no extra control line is required.

Benefits

• 325 l/min nominal flow with a permissible flow of up to 870 l/min.
• 4 to 20 mA current command, safe against wire break and insensitive to voltage drop.
• Internal pilot oil supply and internal pilot oil return, no external pilot line needed.
• Integrated pressure reducing valve, spool symbol W8 with three switching positions across four ports.
• Maximum operating pressure 350 bar, 24 VDC supply, ISO 4401-08-08-0-05 mounting pattern.
• NBR seals, HL hydraulic fluid, installed weight 21.03 kg.

Applications

Vibrating presses, lifting gear and machine tools running on a single power unit manage with internal piloting and need no auxiliary pump. The concealed manual override lets an axis be moved while the electronics stay off. UKCA operation is covered by the electromagnetic compatibility declaration to SI2016/1091.
