Proportional Directional Valve 4WRLE16W8-200LJ-4X/MPT/24F1 - Bosch Rexroth R901558735

In plants with long cable distances between controller and valve, a current command is more robust than a voltage. The 4WRLE16W8-200LJ accepts 4...20 mA and meters 200 l/min nominal from it, controlled by internal main spool position feedback. Its pilot stage is fed and relieved internally, so no additional pilot lines are required at the subplate.

Benefits

• Command value 4...20 mA, cable voltage drop does not distort the value.
• 200 l/min nominal flow with an 800 l/min limit at 350 bar.
• Internal main spool position feedback keeps the characteristic independent of load.
• Pilot oil in and out internally, saving two lines per mounting position.
• Linear characteristic with spool symbol W8, 3 switching positions, 4 ports.
• On-board electronics from 24 VDC, valve weight 11.8 kg.

Applications

The valve suits distributed installations where the cabinet stands far from the hydraulics, for example in steelworks and water engineering drives. Because the pilot stage works internally, it can also sit on simple manifolds without pilot channels. This requires a system pressure that stays above the minimum pilot pressure throughout the cycle.
