Proportional Directional Valve 4WRZE25W8-325-7X/6EG24N9ETK31/A1V - Bosch Rexroth R900950261

Large cylinders want a lot of oil in a short time without the pipework growing out of hand. The 4WRZE25W8-325-7X/6EG24N9ETK31/A1V carries 325 l/min nominal flow on the ISO 4401-08-08-0-05 interface and feeds its pilot stage internally, both supply and return.

Benefits

• 325 l/min nominal flow, up to 870 l/min maximum flow, operating pressure up to 350 bar.
• Internal pilot oil supply and internal return, no external pilot lines.
• Build without a pressure reducing valve, so the pilot stage stays correspondingly simple.
• Spool symbol W8, three switching positions on four ports, plus/minus 10 V command value.
• Concealed manual override for commissioning and fault finding.
• 20.58 kg, FKM seals, 7-pole connector (6 + PE) to EN 175201-804, UKCA conformity.

Technical data

Application

The valve suits presses, forging lines and hydraulic axes with large cylinder volumes. Internal pilot supply assumes a sufficiently high system pressure. Where main pressure fluctuates strongly, a build with an external pilot circuit is preferable.
