Proportional Directional Valve 4WRTE25E1-350L-4X/6EG24ETK31/F1M - Bosch Rexroth R901366874

High flow and accurate stopping only go together when the valve watches the position of its own main spool. The 4WRTE with spool symbol E1 does that with an internal position control loop while delivering 350 l/min nominal flow at 350 bar.

Benefits

• 350 l/min nominal flow, up to 870 l/min maximum, at 350 bar operating pressure.
• Internal position control of the main spool holds the opening steady against flow forces.
• Linear characteristic assigns a fixed opening to every command value, which simplifies loop tuning.
• Internal pilot supply and internal return, so only P, T, A and B have to be piped.
• 4...20 mA command and on-board electronics, 24 VDC supply.

Applications

The valve is used on fast positioning axes in presses, on test benches and in plants with large cylinders. The ISO 4401-08-08-0-05 interface is the size 25 standard, so mechanical replacement of a valve without position control is possible. The valve weighs 17.98 kg.
