Proportional Directional Valve 4WRZ25W8-325-7X/6EG24K4/D3M - Bosch Rexroth R900976328

A central pilot power unit only pays for itself once every main stage hangs on it. The 4WRZ25W8-325-7X is the matching size 25 variant, pilot oil supplied externally and drained externally, 325 l/min nominal flow at 20.39 kg.

Benefits

• 325 l/min nominal flow, with up to 870 l/min passing the main stage.
• External pilot supply and external drain, several axes share one pilot power unit.
• Spool symbol W8 across 4 ports, 3 switching positions, ISO 4401-08-08-0-05 interface.
• 350 bar maximum operating pressure, pilot stage fitted with an integrated pressure reducing valve.
• 20.39 kg weight, NBR seals, commanded at 24 VDC through external electronics.

Applications

The variant goes into presses, stretching lines and test fields where pilot supply is built centrally. If working pressure drops away, switching capability survives on the separate pilot circuit. On the port side it interchanges with the same series in other flow ratings.
