Proportional Directional Valve 4WRTE16W8-220L-4X/6EG24TK31/F1M - Bosch Rexroth R901580693

Where a pilot pump exists but the manifold has no Y line, this plumbing fits without rework. The 4WRTE16W8-220L-4X/6EG24TK31/F1M is fed from outside, drains internally and meters 220 l/min nominal flow at operating pressures up to 350 bar.

Benefits

• External pilot oil supply with internal pilot oil return, no additional drilling required in the manifold.
• 220 l/min nominal flow, maximum flow 460 l/min in size 16.
• 4...20 mA command value, insensitive to cable length across a large installation.
• Spool symbol W8 with a linear characteristic curve, connection diagram ISO 4401-07-07-0-05.
• Operating pressure up to 350 bar, 11.08 kg weight, NBR seals.
• On-board electronics, 24 VDC through a 7-pole (6 + PE) connector to EN 175201-804.

Applications

The valve serves lifting axes on hoisting equipment, lock and weir drives and large clamping cylinders. The internal pilot drain saves a line while the external supply keeps pilot pressure steady. At 220 l/min even long strokes are covered in a short time.
