Proportional Directional Valve 4WRZE25W8-325-7X/6EG24EK31/A1D3M - Bosch Rexroth R900706613

On large cylinders any delay in the pilot stage translates directly into positioning error. The 4WRZE25W8-325-7X/6EG24EK31/A1D3M therefore drains pilot oil through its own line while metering 325 l/min nominal flow at 350 bar.

Benefits

• External pilot oil return keeps shifting time independent of back pressure in the working return.
• Internal pilot oil supply saves the separate feed line to the pilot stage.
• 325 l/min nominal flow against 870 l/min maximum flow, spool symbol W8.
• Analog ±10 V command at the on-board electronics with spool position feedback.
• Integrated pressure reducing valve and UKCA conformity to SI2016/1091, mass 20.62 kg.

Applications

Suited to large presses, lift tables and test rigs with a collecting return, return filter or oil cooler. The separated pilot oil return keeps cycle times repeatable. Mounting pattern ISO 4401-08-08-0-05, HL hydraulic fluid.
