Proportional Directional Valve 4WRKE25E350L-3X/6EG24K31/A1D3M - Bosch Rexroth R900973369

When replacing a valve in an existing axis, what counts is that the signal and the pilot oil routing stay as they were. The 4WRKE25E350L-3X/6EG24K31/A1D3M takes over the plus minus 10 V command and the external pilot routing one to one, at 350 l/min nominal flow and 350 bar operating pressure.

Key benefits

• Plus minus 10 V command into the on-board electronics, 24 VDC supply, no separate amplifier card needed.
• 350 l/min nominal flow, maximum flow 870 l/min, size 25.
• External pilot oil supply and external return match power units with a separate pilot pump.
• Spool symbol E, 3 switching positions, 4 ports, connection pattern ISO 4401-08-08-0-05.
• Internal spool position feedback, linear characteristic curve, 17.85 kg weight.
• NBR seals for HL hydraulic fluid, 7-pole connector (6 + PE).

Applications

The version replaces older proportional valves in presses and forming lines without anyone touching the control cabinet. At 350 l/min nominal flow it serves main cylinders of medium bore. Interface and size 25 follow the widely used ISO 4401-08-08-0-05 hole pattern.
