Proportional Directional Valve 4WRZ25W8-325-7X/6EG24N9EK4/D3V - Bosch Rexroth R900947003

Not every machine owns a pilot circuit. The 4WRZ25W8-325-7X/6EG24N9EK4/D3V therefore works with internal pilot supply and routes the pilot stream through an external drain, at 325 l/min nominal flow and 350 bar operating pressure.

Advantages

• 325 l/min nominal flow, 870 l/min as the limit in size 25.
• Internal pilot supply, external pilot drain, no pilot pump needed and the drain stays relieved.
• 20.34 kg mass, spool symbol W8 and three switching positions with concealed auxiliary actuation.
• ISO 4401-08-08-0-05 pattern, size 25, rated up to 350 bar operating pressure.
• Connector, 3-pole (2 + PE) for the electrical link, 24 VDC supply.
• 20.34 kg mass, FKM seals, HL grade fluid.

Applications

Typical installations are presses, test rigs and stretching lines that run on one pump circuit. Because the pilot stage lives off the main pressure, that pressure must be present during control. The external drain is routed to an unpressurised line.
