Proportional Directional Valve 4WRTE25W8-220L-4X/6EG24K31/F1M - Bosch Rexroth R901155089

When an older controlled axis is renewed, the existing X and Y lines on the manifold should stay exactly as they are. This 4WRTE with spool symbol W8 is piloted externally and drained externally and controls 220 l/min nominal flow at 350 bar.

Benefits

• Fully external pilot routing fits manifolds with existing X and Y ports.
• Internal position control of the main spool with a linear curve replaces the feedback of a servo valve.
• 220 l/min nominal flow at 350 bar, up to 870 l/min maximum.
• On-board electronics at the valve remove the need for a separate amplifier stage.
• ISO 4401-08-08-0-05 interface with four ports and three switching positions.

Applications

The version is intended for renewing controlled axes on presses, test benches and forming machines. Before the conversion the signal type of the existing control should be checked against the 4...20 mA command input. The valve weighs 18.04 kg and runs on HL hydraulic fluid.
