Proportional Directional Valve 4WRKE10W8-25L-3X/6EG24K31/F1D3M - Bosch Rexroth R901407221

An infeed axis can only be guided as precisely as its nominal flow allows. The 4WRKE10W8-25L-3X/6EG24K31/F1D3M therefore works with 25 l/min nominal flow in size 10 and closes the loop on the spool through internal position feedback against a 4...20 mA command.

Benefits

• 25 l/min nominal flow in size 10, suited to axes that approach short distances accurately.
• 4...20 mA command signal, the current loop stays quiet over long cable runs and a broken wire shows up as 0 mA.
• Pilot oil supplied and drained externally, the pilot stage stays decoupled from the main channel.
• 315 bar maximum operating pressure on the ISO 4401-05-05-0-05 pattern, flow up to 150 l/min.
• Spool symbol W8, 8.42 kg, on-board electronics running at 24 VDC through a 7-pole (6 + PE) plug.

Applications

The valve serves feed and infeed axes of machine tools, test rigs and handling equipment with small cylinders. External pilot routing allows operation on systems whose main pressure fluctuates widely. As a spare part it fits any subplate to ISO 4401-05-05-0-05.
