Proportional Directional Valve 4WRLE25E1-400LJ-4X/MPY/24A1 - Bosch Rexroth R901471420

Existing controls often supply ±10 V while the return line still carries back pressure. For that case there is the 4WRLE25E1-400LJ-4X/MPY/24A1, which regulates 400 l/min at up to 350 bar and discharges its pilot oil externally through Y.

Benefits

• Voltage command value ±10 V connects to existing controller cards without rework
• External pilot return through Y stays reliable even with raised tank pressure
• 400 l/min nominal flow instead of 350 l/min in the same envelope
• Spool symbol E1 with three switching positions and four ports
• Internal spool position measurement, operating pressure up to 350 bar
• Mass 19.42 kg, CE conformity, NBR seals

Applications

The variant replaces older valves in presses and test rigs whose controls are built for voltage commands. It supplies more flow than the 350 l/min step without the subplate having to change. The external pilot return protects the pilot stage from back pressure.
