Proportional Directional Valve 4WRTE25W6-220L-4X/6EG24K31/A1M - Bosch Rexroth R900700274

Larger machines feed all pilot stages from a separate small circuit at constant pressure. This 4WRTE25W6-220L-4X takes pilot oil from there and returns it there, while the working circuit moves up to 870 l/min at 350 bar.

Benefits

• External pilot oil supply and external return for operation on a central pilot power unit
• 220 l/min nominal flow, 870 l/min maximum flow
• Spool symbol W6, three switching positions, four ports
• Analog ±10 V command value, on-board electronics, 24 VDC
• ISO 4401-08-08-0-05 interface, 350 bar operating pressure, NBR seals

Applications

Used on press lines, rolling stands and test installations with several controlled axes on one power unit. Constant pilot pressure from the pilot circuit gives every valve the same switching behaviour. At 220 l/min nominal flow, resolution stays high across the working range.
