Proportional Directional Valve 4WRLE16W8-200LJ-4X/MXY/24A1 - Bosch Rexroth R901404334

Existing control blocks often already carry pilot channels, and then the externally piloted version is the right pick. The 4WRLE16W8-200LJ takes pilot oil through X, drains through Y and works from a plus/minus 10 V voltage command. At 200 l/min nominal and an 800 l/min limit, internal position feedback trims the main spool.

Benefits

• External pilot through X and Y, matching manifolds that already have these channels.
• 200 l/min nominal flow, limit 800 l/min, operating pressure 350 bar.
• Internal main spool position feedback, linear characteristic with symbol W8.
• Command value plus/minus 10 V through the 7-pole connector to EN 175201-804.
• Valve weight 11.6 kg, mounts to ISO 4401-07-07-0-05.
• On-board electronics, 24 VDC supply, CE conformity.

Applications

The variant goes into conversions and modernisations where manifold and piping are to be kept. It equally suits new builds with central pilot supply, for example in rolling mills and press lines. Before fitting, check that the pilot pressure at X lies within the permitted range of the 4WRLE series.
