Proportional Directional Valve 4WRZE10W6-25-7X/6EG24N9ETK31/F1M - Bosch Rexroth R901448766

The 4WRZE10W6-25-7X/6EG24N9ETK31/F1M is the 25 l/min step of the series and works with internal pilot oil supply and internal pilot oil return. The manifold therefore needs no extra pilot channels, at operating pressures up to 315 bar.

Advantages

• Nominal flow of 25 l/min for small, slowly controlled axes
• Internal pilot oil supply and internal pilot oil return, no separate channel in the block
• Operating pressure to 315 bar, maximum flow 170 l/min
• W6 spool symbol with 3 switching positions across 4 ports
• Concealed auxiliary actuation, built without a pressure reducing valve
• On-board electronics, 4 to 20 mA command value, 24 V DC supply

Applications

The plate makes sense on infeed axes, clamping units and positioning drives that rarely draw more than 25 l/min. With both pilot paths internal, manifold design gets simpler and the number of sealing faces drops. NBR seals are fitted for HL hydraulic fluid.
