Proportional Directional Valve 4WRZE10W8-85-7X/6EG24N9ETK31/F1M - Bosch Rexroth R900764372

Jacking cylinders in tunnelling sit far from the cabinet, where every extra line costs time and space. The 4WRZE10W8-85-7X/6EG24N9ETK31/F1M therefore works from a 4...20 mA current command, routes pilot oil supply and return internally and regulates 85 l/min nominal flow through spool symbol W8.

Benefits

• Internal pilot oil supply and internal return, pipework limited to four ports.
• Current command 4...20 mA, resistant to interference over long cable runs inside a structure.
• Spool symbol W8 with 85 l/min nominal flow, maximum flow 170 l/min.
• Version without pressure reducing valve, concealed auxiliary actuation fitted.
• Operating pressure up to 315 bar, size 10, weight 8.03 kg.

Applications

Jacking and shoring cylinders, pipe jacking rigs and lifting jacks in civil engineering work in confined spaces. Internal pilot routing plus the current interface keep the number of connections low. The subplate mounting to ISO 4401-05-05-0-05 stays compatible with the rest of the series.
