Proportional Directional Valve 4WRTE27W8-500L-4X/6EG24ETK31/A1M - Bosch Rexroth R901485962

High flows appear where cylinders with large swept volume have to travel fast. The 4WRTE27W8-500L-4X/6EG24ETK31/A1M supplies 500 l/min nominal flow in size 27 for that, pilots internally and works at operating pressure up to 270 bar.

Benefits

• 500 l/min nominal flow, with 1000 l/min as the maximum flow of the range.
• Internal pilot oil supply and internal return, allowing a power unit without a pilot pump.
• Symbol W8 with three switching positions and internal spool position feedback.
• Command value ±10 V DC, supply 24 V DC through a 7-pole connector (6 + PE).
• Operating pressure up to 270 bar, weight 19.5 kg, mounting pattern ISO 4401-08-07-0-05.

Applications

The valve controls main axes in presses, plastics machinery and lifting gear with high oil demand. Because the permitted operating pressure is 270 bar, it belongs in circuits designed below the 350 bar class. Internal piloting keeps the work on the hydraulic manifold small.
