Proportional Directional Valve 4WRLE25E400LJ-4X/VPT/24A1 - Bosch Rexroth R901503389

For hydraulic fluids that call for FKM seals, this 4WRLE25 moves 400 l/min nominal flow with an internal pilot oil circuit. Symbol E spool, maximum flow 1250 l/min, operating pressure up to 350 bar, weight 19.32 kg.

Advantages

• 400 l/min nominal flow at a maximum flow of 1250 l/min
• Internal pilot oil supply and return removes the need for external pilot lines
• Internal piston position feedback keeps the spool exactly at the commanded position
• FKM seals suit chemically more demanding hydraulic fluids
• Analog control with a ±10 V command value through the on-board electronics
• 19.32 kg at size 25 to ISO 4401-08-08-0-05, CE compliant

Applications

The valve is used where the hydraulic fluid requires FKM seals, for example at elevated operating temperatures or with certain additives. Internal pilot oil routing keeps piping at the mounting surface to a minimum. Internal piston position feedback gives repeatable control behavior of the spool.
