Proportional Directional Valve 4WRTE25V1-350L-4X/6EG24K31/F1V - Bosch Rexroth R901525408

When the control cabinet sits far from the axis, a current command value is the more interference-tolerant choice. The 4WRTE25V1-350L-4X/6EG24K31/F1V takes an analog 4 to 20 mA command value and meters a nominal flow of 350 l/min in size 25 at a maximum operating pressure of 350 bar.

Benefits

• Analog command value of 4 to 20 mA, a current signal stays readable over long cable runs.
• Nominal flow 350 l/min, maximum flow 870 l/min, maximum operating pressure 350 bar.
• Spool symbol V1 with a linear characteristic, three switching positions across four ports.
• External pilot oil supply and external pilot oil return, so the pilot stage does not follow the working pressure.
• On-board electronics with spool position feedback, 24 VDC supply through a 7-pole connector (6 + PE) according to EN 175201-804.
• Subplate mounting to ISO 4401-08-08-0-05, FKM seals for HL hydraulic fluid, weight 17.92 kg.

Applications

The valve is built into large axes of presses, test rigs and forming machines whose controller sits in a remote cabinet. Its own pilot circuit keeps the pilot stage clean when the main circuit fluctuates. With the ISO 4401-08-08-0-05 pattern it fits the usual size 25 subplate.
