Proportional Directional Valve 4WRZE16W8-125-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R901480082

In electrically noisy surroundings a current command value is the sturdier choice. The 4WRZE16W8-125-7X in size 16 is driven by 4...20 mA, carries 125 l/min nominal flow and limits its pilot pressure through an integrated pressure reducing valve at up to 350 bar operating pressure.

Benefits

• A 4...20 mA command value stays immune to interference over long cables, and a broken wire shows up at zero.
• 125 l/min nominal flow, with peaks of up to 460 l/min.
• Internal pilot oil supply and internal pilot oil return save two external lines.
• The integrated pressure reducing valve stabilises pilot control independently of system pressure.
• Concealed auxiliary actuation helps during commissioning, three switching positions use spool symbol W8.
• 12 kg mass, FKM seals and UKCA marking under SI2016/1091.

Application

The type fits axes in forming plants and hydraulic test rigs whose controller sits far away in a cabinet. Against the 180 version, nominal flow is lower while resolution in the fine range is higher. Connection diagram and dimensions follow ISO 4401-07-07-0-05.
