Proportional Directional Valve 4WRZE25W6-325-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900954681

Routing pilot oil internally saves a separate control line inside the power unit. The 4WRZE25W6-325-7X/6EG24ETK31/A1D3M works with internal pilot oil supply and internal pilot oil return, meters 325 l/min nominal flow at 350 bar operating pressure and shapes the flow through spool symbol W6.

Benefits

• Internal pilot oil supply and internal return, so no separate pilot circuit is needed.
• Nominal flow 325 l/min with up to 870 l/min possible through the valve.
• Operating pressure up to 350 bar on the size 25 mounting pattern ISO 4401-08-08-0-05.
• On-board electronics handle the analog ±10 V command value at the valve, supplied from 24 VDC.
• Pilot-operated spool valve with a pressure reducing valve in the pilot stage, three switching positions.
• Connected through a 7-pole connector (6 + PE) to EN 175201-804, mass 20.55 kg.

Applications

The valve serves presses, injection moulding machines and test rigs whose cylinders call for large oil volumes under stepless control. Spool symbol W6 suits axes that ramp out of centre position in both directions. Internal piloting assumes a main circuit that stays under pressure.
