Proportional Directional Valve 4WRTE25W8-350P-4X/6EG24EK31/F1M - Bosch Rexroth R901011134

Where filters or return coolers load the tank line with back pressure, pilot oil should take its own route. The 4WRTE25W8-350P-4X/6EG24EK31/F1M draws pilot oil internally from the pressure port and discharges it through an external return, at 350 l/min nominal flow.

Benefits

• Internal supply with external pilot return keeps the pilot circuit clear of back pressure.
• Spool symbol W8 with 3 switching positions for equal opening in both flow directions.
• 350 l/min nominal flow at operating pressures up to 350 bar.
• A 4...20 mA command stays stable over long cable runs, supply 24 VDC.
• A 7-pole connector (6 + PE) to EN 175201-804, mounting pattern ISO 4401-08-08-0-05, 18 kg.

Applications

The valve serves motor drives and through-rod cylinders in plants whose return line is heavily loaded, for instance behind coolers and fine filters. Internal spool position feedback makes flow follow the signal even under load changes. NBR seals suit mineral oil of class HL.
