Proportional Directional Valve 4WRLE25R3-350SJ-4X/MPY/24F1 - Bosch Rexroth R901583318

Fast reversal and gentle approach usually exclude each other on a linear characteristic, but not on a progressive one. The size 25 4WRLE uses that curve, passes up to 1250 l/min maximum flow at 350 bar and controls the main spool through internal position measurement.

Benefits

• Up to 1250 l/min maximum flow on the size 25 interface ISO 4401-08-08-0-05.
• Progressive curve combines fine approach in the small command range with a fast stroke.
• Internal position feedback of the main spool keeps the opening independent of flow forces.
• 4...20 mA command with live zero for line monitoring.
• Internal pilot supply with external pilot return, 350 bar operating pressure.
• CE conformity, on-board electronics, 24 VDC supply.

Applications

The valve is intended for fast axes in forming machines, for servo hydraulic test benches and for plants with short cycle times. The high maximum flow allows large piston speeds without running several valves in parallel. Sealing is NBR for HL hydraulic fluid, and the valve weighs 18.58 kg.
