Proportional Directional Valve 4WRTE10W8-25L-4X/6EG24EK31/F1M - Bosch Rexroth R901446035

Long cable runs between controller and valve are where analogue voltage commands lose accuracy. The 4WRTE10W8-25L-4X/6EG24EK31/F1M therefore works on a 4...20 mA current command and meters a 25 l/min nominal flow in size 10.

Advantages

• Current command 4...20 mA, tolerant of voltage drop and electrical pickup over long cable runs.
• A broken wire shows up as 0 mA because the useful range only starts at 4 mA.
• Nominal flow of 25 l/min at operating pressures up to 350 bar.
• Internal pilot oil supply with external pilot oil return, so the X line at the manifold is no longer needed.
• Spool symbol W8, three switching positions, four ports, connection diagram ISO 4401-05-05-0-05.
• Weight of 8.46 kg, NBR seals, 24 VDC supply voltage.

Applications

The valve fits power units whose controller sits in a remote cabinet. Internal pilot supply saves the separate pilot line as long as port P carries sufficient pressure at all times. The external return leads pilot oil back without back pressure, even when the tank line carries a residual head.
