Proportional Directional Valve 4WRTE25W8-350L-4X/6EG24ETK31/F1M - Bosch Rexroth R901121430

Short cycle times depend not only on flow, but also on how much oil has to be moved in the pilot circuit. This 4WRTE routes pilot oil entirely internally and puts 350 l/min nominal flow at 350 bar onto the axis.

Benefits

• 350 l/min nominal flow at 350 bar, maximum flow 870 l/min.
• Internal pilot supply and internal return keep the pilot circuit short.
• Internal position control of the main spool secures the setting against flow forces.
• Linear characteristic with a 4...20 mA command and on-board electronics.
• 18.04 kg on the ISO 4401-08-08-0-05 interface.

Applications

The valve is used on presses and test benches with a high cycle count and on axes that reverse frequently. Internal piloting requires a system pressure above the minimum pilot pressure. Sealing is NBR for HL hydraulic fluid.
