Proportional Directional Valve 4WRZE25E325-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R901208568

Where no separate control circuit exists, pilot oil has to come out of the main channel and be brought down to a level the pilot stage can take. This version does both inside the valve, works without X and Y lines and controls 325 l/min with spool symbol E.

Benefits

• The pilot stage is fed and drained internally, so no additional lines have to be routed.
• A pressure reducing valve in the pilot line caps the internally tapped pilot pressure.
• Nominal flow of 325 l/min at an operating pressure of up to 350 bar.
• Spool symbol E, three switching positions, four ports, NBR seals.
• Current command 4...20 mA into on-board electronics, 24 VDC, mass 20.52 kg.

Applications

This variant is built for compact power units without a separate pilot pump, for instance on stand-alone machines and retrofit solutions. The manifold carries only the four main ports, everything else happens inside the valve. The UKCA entry to SI2016/1091 covers electromagnetic compatibility.
