Proportional Directional Valve 4WRLE16W6-200LJ-4X/MXY/24L1 - Bosch Rexroth R901487037

The pilot stage of a size 16 valve is fed most reliably from its own source. This 4WRLE16W6-200LJ does exactly that, taking pilot oil externally at X and draining externally at Y regardless of what the working circuit does. Control runs over IO-Link on the 5-pole M12 connector, and hydraulically it meters 200 l/min nominal at an 800 l/min limit.

Benefits

• External pilot supply and external drain decouple pilot pressure from working pressure.
• IO-Link on M12 x 1 with A coding, digital parameter setting and diagnostics.
• 200 l/min nominal flow at an 800 l/min limit and 350 bar.
• Internal main spool position feedback, linear characteristic with symbol W6.
• On-board electronics, 24 VDC supply, CE conformity.
• Valve weight 12.4 kg, NBR seals for HL fluid.

Applications

The valve runs forming presses, roll adjustment drives and test rigs with a separate pilot power unit. Over IO-Link the characteristic and ramps can be changed from the control system without opening the valve. Pilot pressure at X must stay within the permitted range of the 4WRLE series.
