Proportional Directional Valve 4WRZE10W8-25-7X/6EG24N9ETK31/F1M - Bosch Rexroth R901269015

Metering and feed axes work with small oil volumes but often with long signal runs. The 4WRZE10W8-25-7X/6EG24N9ETK31/F1M therefore combines 25 l/min nominal flow through spool symbol W8 with a 4...20 mA current command and places pilot oil supply as well as return inside the valve.

Benefits

• Nominal flow 25 l/min through spool symbol W8, maximum flow 170 l/min.
• Current command 4...20 mA stays unambiguous even over long cable runs.
• Internal pilot oil supply and internal return, version without pressure reducing valve.
• Concealed auxiliary actuation on the pilot valve, operating pressure up to 315 bar.
• Size 10 to ISO 4401-05-05-0-05, weight 8.7 kg, NBR seals.

Applications

Metering axes in coating and bonding plants as well as feed units in assembly lines move exactly these flows. The small nominal flow makes short strokes easy to control. Through the current interface a broken cable reports itself to the controller as zero current.
