Proportional Directional Valve 4WRLE25E1-400LJ-4X/MPY/24F1 - Bosch Rexroth R901509427

If an axis needs spool symbol E1 and more than 350 l/min at the same time, the 4WRLE25E1-400LJ-4X/MPY/24F1 is the answer. It regulates 400 l/min nominal flow at up to 350 bar and discharges pilot oil externally through Y, so the pilot stage stays clear of return pressure.

Benefits

• 400 l/min nominal flow, roughly 14 percent more than the 350 l/min build of the same size
• Spool symbol E1 for applications where the W symbols do not fit
• External pilot return, therefore insensitive to back pressure in the tank circuit
• Current command value 4 to 20 mA, with wire break visible immediately as zero current
• Maximum size 25 flow of 1250 l/min held in reserve
• Mass 19.32 kg, CE compliant, NBR seals, HL hydraulic fluid

Applications

The build sits on large feed and lifting axes in presses and forming plants. At 400 l/min rapid traverse can be covered without an extra valve. The current interface pays off where signal and power cables share the same duct.
